@@mohitgoenka99 hello sir can you please take up this problem . A charge q0 is distributed uniformly on a ring of radius R. A sphere of equal radius R is constructed with its centre on the circumference of the ring. Find the electric flux through the surface of the sphere. using formula the answer doesnt match the one in the key
Just amazing, what can I even say. It will be highly appreciated if more PhD series videos are uploaded, would be really helpful for JEE 2023. Thank you sir
Hello there! I am a NEET aspirant and i saw your comment about question 2 coming in JEE adv 2024! Can't this question be solved by simple symmetry? Like taking difference: flux through entire cylinder (ie Q/Eo) - flux through the two cones with there vertex at center (at charge q)? Moreover , is this topic a necessity or an alternative? As I even found its mention in HCV
@@Niru_24105 Yes that's what we are doing. We are finding difference between the total flux and the flux through the two flat surfaces. But to find the flux through the two flat surfaces by a *point charge*, use of solid angle simplifies the problem. As you may know that flux is nothing but QΩ/4piε0 (Ω is solid angle) And then we can use symmetry to find through the other one. And I would suggest you know the concept of solid angle (though not necessary) since many questions of intensity in geometrical optics can also be solved by this easily. And as I am a JEE aspirant I can certainly tell you that most of the institutes teach solid angle to Jee students
@@vidhandoshi6623 thankyou 💙!!! Ever since NTA did all that, every NEET aspirant is a low key JEE aspirant too😅, the reason why I too am here ! Meanwhile just asking , was this your first attempt? how did your Mains go?
@@Niru_24105 😅 I will give my JEE next year I am in class 12th right now. And all the best to you too. I know the nta scam has become a big issue right.
Sir ek request hai jaise apne Eduniti Gold mine document mei Formula Revision ke section mei class 12th ke saare topics cover up krwa diye waise hi class 11th ke bhi kuch kuch chapters bache hai jaise centre of mass, Kinematics (2D and 3D), Fluids, Properties of Matter, Laws of motion, collision, aur Thermal Properties. Sir meri aur meri 35 friends ki guzaarish hai kindly pls in videos ko bnane ke bad PhD series ke saath continue kare (Though the PhD series is excellent still we need the formulae revision videos more since fEb attempt is fast approaching.) Sir I hope that you will consider me and my friends' request. Yours Sincerely, Gaurav
Sir, in the master pdf which you have provided, formulae series of 5 chapters from 11th are not uploaded. 🙏Plzz tell when will they be uploaded sir. It's a humble request 🥺
Sir I was solving final lap problem and stuck in one question that involves the concept of solid angle so came here to revise but one of my old doubt of question 3 get cleared. Thankyou sir
Sir it was so good video everything is clear now It's a request to kindly take concept and advanced problems relating guass law next for PhD session thank you 😀
This was such an amazing session sir… for the first time I could actually visualise and understand solid angle.. otherwise I just memorised it’s formula and basic application but today saw the actual derivation and use of it. 😁
hello sir can you please take up this problem . A charge q0 is distributed uniformly on a ring of radius R. A sphere of equal radius R is constructed with its centre on the circumference of the ring. Find the electric flux through the surface of the sphere.
Agar radius ke dwara banaya hua curved surface area 10 unit square hai , aur agar usi radius ke dwara banaya hua dusra curved surface area 10 unit square hai but iss baar dimensions alag hai surface area ka .mtlb iss baar length bahut jyada hai aur width Kam hai , lekin area utna hi hai 10 unit square , to kya iss case me dono ka solid angle same hoga
Sir I have a doubt. In chapters like Nlm, Friction generally all the PYQ's can be solved by basic theory and understanding but there are a lot of advance pulley/constraint problems taught to us in coaching . Is it Ok to leave them for jee mains ?
Sir please ek element leke pure body ka mass,charge and other quantities nikalne wale pe bhi ek phd video bana dijiye as it will be so much helpful for adv point of view in many chapters ,please sir👏🏼
sir please make rbs series continue 2022 and after completing it start new series of mixed questions and sir please tell us name of channel like yours for chemistry and maths if you knowas we need this type of content for math and chemistry also
@@mohitgoenka99 ok sir thanks for the clarification❣️ Sir mein soch raha hu ki modern phy semi conductors wala part kark rakh du practice k liye pyqs kitne year ka karu?? Atleast
Sir ek problem aa rhi hai ki like mene koi chapter pdha use revise kiya fir nya chapter start kiya pr jb tk dusra chapter end hota hai tb tk phla ya fir usse phla chapter bilkul dimag se gyb ho jata hai.. so sir apke anusar kya krna chahiye?? ... Kyuki sir coaching test ke wqt jb chapter revise krne ka tym ata hai to bhut sara chapter ho jata hai or fir cover nhi ho pata.
For such time, your own hand written short notes are required dear. Short notes were in 3-4 pages you complete electrostatics, in 1 page you complete gravitation etc. Keep revising them once a week.
@@mohitgoenka99 Thank u sir...apki wajah se ajj mere preparation 0 par hoo ke bhi sare concept samjha pa raha nhu ..or sare chapters apse hi karunga thenn jee mai acha percentile launga......love u sir ❤️❤️
Sir could you please do the same for Capacitor circuit that are generally asked in jee main..charging discharging of Capacitor at time t=0,t=t..questions like that
sir is it really possible to acheive a rank under 3.5k in jee advanced after cracking mains with 95-97 percentile (considering we get 3 to 4 months purely for advanced)
