@@shadytin328 Alakh sir is a very great teacher..and he also use HCV(Concepts of physics) for his study........then, you can imagine the potential of HC VERMA SIR.....I respect both the legends🏹
@@shadytin328 for ur kind information I am also a subscriber of YAKEEN and LAKSHYA batch😊....I m not telling he is not a legend but there is no sense to tell about him in HC Verma channel
To help the students of class 11,12 in physics topics , there is a physics channel where u can post ur doubts in comment section or by email and u will get good explanation of your doubts in the form of a video . Question may be of JEE or NEET as well. Try once ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-4WAzK7XCg0w.html This is the link for one of such videos

Thank you so much sir me abhi yahi topic aj padne jarrha tha Meri kismat kitni acchi hai apne ajjhi ye video dal diya Thank you so much sir #GOD OF PHYSICS
Sir please make videos on detail of error analysis. As how to do when error is less than least count of the instrument. Error analysis is quite difficult to do many times.
#hcv sir please make chaiterwise lectures of iit jee physics for concepts as well application of those concepts to problem. If you can make this it will be a great treasure of physics for those students who are somehow not able to pay fees of costly school and coachings as well for physics learners too it will be beneficial.
Sir please explain 🙏🙏🙏🙏🙏🙏Sir I am in class 11th and I am confused so I want to ask a question - please explain it. A particle moves along a straight line OX. At a time t (in sec. ), the distance x(in m) of the particle O is given by x = 40 + 12t - t^3. How long would the particle travel before coming to rest ? Sir I am confused b/w the answer 56 m or 16 m, which is the correct answer ? Sir please explain and clear the concept ?
correct ans is 16m. My students concept is very clear regarding this tricky question. Explanation : at t=0, x=40m at v=0, t=2, and x= (40+16)m so from t=0 to t=2 net distance = (40+16) - (40) = 16m. 🙂
Sir is there is any possibility, A heavy objects like car can start (mean show deflection) , when Detect electromagnetic waves?? ?? Plz sir Bata dijiye
Sir agar apko etna intrest h baccho ko padhane mei toh ap unacadmey plus pe aajayie, aur baccho ko jee ke liye guide kriye... We need a teacher like you badly 😔 By the way I'm a 2022 jee aspirant
Sir i have one question ..... agr michelson Morley experiment mein practically bhi 0.4 ka fringe shift milta toh kya conclusion nikalta.. .....suppose ki Michelson Morley experiment ka theoritical result practical result ke equal hota ..toh kya conclusion nikalte firr ???? Please answer sir Jb theoritical result practical result ke barabar nhi tha ...toh conclusion nikla ki ether exist nhi krta ...or light ki speed sbhi intertial frame ke liye constant h ..C hi h ....toh jb barabar result nikalte firr kya hota ???
According to me if practical and theoretical results matchs then we can say that ether exits and also we get the speed of ether with respect to sun and we can consider ether as absolute frame of reference.
@@aniketraghuwanshi2674 why you are thanking man it is our responsibility to make physics clear for everyone so that we can expand our knowledge and understanding.
GREETINGS SIR, I AM PULKIT FROM HARYANA. I AM A STUDENT OF CLASS 10TH SIR MY QUESTION IS THAT, REFRACTIVE INDEX IS RATIO OF SPEED OF LIGHT IN MEDIUM 1 AND MEDIUM 2 THIS MEANS THAT SPEED OF LIGHT VARRIES IN DIFFERENT MEDIUMS, BUT 'SPECIAL THEORY OF RELATIVITY' STATES THAT SPEED OF LIGHT IS CONSTANT EVERYWHERE AND IN ALL MEDIUMS. "POSTULATE 2" ?
HELLO SIR, I AM KHUSHI AND STUDY IN 12TH PCM.....🙂🙂🙂🙂🙂🙂 I WAS STUDYING CH MAGNETISM AND IN THAT CH I GOT A DOUBT WHICH IS VERY CONFUSING FOR ME.... THAT QUE IS THAT... SCIENTISTS HAVE SAID THAT EARTH🌍 PRODUCES MAGNETISM SINCE IT ROTATES AND IONS PRODUCES CURRENT AND THAT CURRENT PRODUCES MAGNETIC FIELD. THE PROBLEM IS " IF EARTH PRODUCES CURRENT THEN WHY WE DONT GET SHOCK FROM THE EARTH, INSTEAD OF THE CLOUDS?" WHY WE DONT EXPERIENCE THAT CURRENT? PLEASE SIR I REQUEST YOU TO SOLVE MY DOUBT...........🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏
Magnetic field produced by earth is very low. So current that produces magnetic field is also very low. Hence No Shock. There are current within our body too.. every neuron has MICRO current. But we don't get shock.. Infact we need them.
Dear hc Verma sir ,in your book part 2 ,chapter-electric current in conductors, the last problem can be done by using integration.Others are using the concept of discharging and charging at some time.please help
Sir i am sandip biswas from bethuadahari , nadia district of west bengal. Sir my question is that in space having no any obstacles which can disturbing the light , then why speed of light is not be infinite. Why it is constant 3x10^8.
Sir we study in class 12 that electromagnetic wave is produced when it is passed through electric and magnetic fields but if we go to see like this then in vacuum no electric and magnetic fields are present in vacuum then why we say ultraviolet rays as electromagnetic wave? As we know only gravitational field surrounds the earth. Is it real from above we can conclude that gravitational field is equivalent to the sum of electric and magnetic field or vacuum is a state of matter which is providing it electric and magnetic field
Sir i have a question that " In michelson-morley experiment we get that fring shift is directly proportional to (L1 + L2)(v^2) but according to Albert Einstein speed of light is constant that implies that v (where v is relative speed of earth with respect to ether) is always zero it means that if we change the L1 and L2 then also we can't get fringe shift but practically we are getting fringe shift so the conclusion is that either there is somewhere mistake in calculation or the michelson-morley experiment is irrelevant. " please answer me.
One more thing ....agr theoritical practical result match ho jaate ...toh kya yeah conclusion nikl skta tha ...ki speed of light alag alag frames ke liye alag alag rhegi ??? Agr dono result match hote tb ....
Mere third comment ka bhi answer de dena ...ki kya speed of light alag alag frames ke liye different rheti agar Michelson Morley mein theoritical or practical result barabarr hote tb???
@@aniketraghuwanshi2674 yes because if you see the caculation in one arm we are taking speed of light c+v when light is moving towards mirror and c-v when light is moving towards semi reflective lens . Here c+v and c - v are speed of light with respect to ether and v is speed of earth with respect to ether .
No... i think you should only perfect your newtonian mechanics as applying lagrangians in jee questions will only waste time.. which otherwise could be solved in less time with newtonian mechanics.
Sir I don't get the point that in addition and subtraction we simpally add the errors but in multiple or division we use fractional error to calculate the resultant and error, why? Why fraction error?
@@nishant6148 ohhk.. then it requires detailed explanations. i will soon be uploading this chapter. You can check them later. Right i have plans to upload Laws Of Motion
that would be really great but as far as I know sir, he won't bcz sir loves Core Conceptual Physics. Also considering his age, Sir has already served so much.. so precious gem of INDIA 🙏
Sir I want to ask some questions to u. How can I ask to u..this question is not from book as I'm student of class 12 I had not read this type of qúestion never sir I think many of student had not think about it. This question is arise from my mind. Please sir if u read my comment please 🙏🙏🙏🙏🙏🙏 reply and give me way to ask this question from u
Sir My name is Subham Hati from West Bengal . I searched your video to clear my doubt. Even whole internet is unable. Please help. My question is "If the area of a circle is increased by 69% then what is the percentage increase of the radius"? Now , ans is 30% looks easy. When I am applying A =πr² →∆A/A = 2∆r/r → ∆A/A ×100 = 2 ∆r/r ×100 → 69% = 2 × ∆r/r % →∆r/r% = 34.5% How this can be possible. I have been thinking since 24 hours , please help sir. Jay shree ram ❤
According to relativity space and time are interlinked but some theories like String field theory believes that space can be ended but it's not in 3rd dimension.
If you take a gaussian closed surface around magnet then total lines leaving from is equal tontoal lines entering south so net flux is zero. This means net magnetic charge should be zero inside. So if there is north there should be south pole simultaneously. North south cant exist separately
