SIR , my name is anant of class 10 my doubt is that we know that flowing electron in a wire experiences resistance but what if electron is showing its wave nature does than he will experience resistance?? ( actually i do not know anything about its wave nature so my question could be silly).
Good day sir. i have a doubt in electrostatic potiential. We generally add potiential algebraically depending on the sign of the charge. By this logic the midpoint in the dipole should have 0 potiential, which is true. BUT sir how come the potiential energy, that is the product of test charge and potiential non zero in the midpoint. IF the potiential is 0 then the potiential energy must be 0, then the charge must be stable and not move from the midpoint of the dipole when we let it go. but it moves towards the negative or the positive part of the dipole. please kindly clarify my doubt sir.🙏
Kisne bola potential energy zero nhi h potential energy zero h but equilibrium m hone ki first condition Force ka zero hona hoti h jo dipole m kabhi nhi hota
Sir , i have a question From class 9th motion ch-7 The question is "Derive the equation for the displacement of an object under uniform acceleration, showing that the displacement s after time t is given by s=ut+1/2at^2 , where u is the initial velocity, a is the constant acceleration, and t is the time interval."
Dear Sir how does a capacitor works in an AC current? Does it really store charge as the polarity changes time to time.? And how does capacitor gets charge by DC current also if DC current does not have any angular frequency.. Please enlighten my wandering soul.
Sir ,I have a question from light chapter of class 10. In case of object at infinity (specific with concave mirror) , why we draw its height on both positive and negative side of the principal axis ... Since as per sign convention , it's height would become zero in this way as +Positive (-negative)=0 ?? Please answer to make it clear for me and my classmates..
Sir , I read your book and have a question from friction.If friction is electrostatic force then friction force is directly proportional to the no. of contacts between the atom or molecules of two surfaces which is directly proportional to the surface area.But as we know friction force do not depend on contact area???
Bhai pehli baat to tumne shi se nhi samjha friction ko , friction depend krta h sirf mass par ,jitna jyada body weight hoga, utna hi jyada uske spikes dusri surface ke ander ghusnege and us se jyada friction hoga . Assume ki 2 same weight ki body hai Ek ka contact surface area jyada hai to contact spikes bhi jyada hogi ,jis se vo weight distributed jo hoga ek spike par km ayega compare to jiska area km hai ,means vo ander km ghusengi,lekin dusre wali jo hai vo jyada ghusengi lekin usme contact surface km hai . Dono cases me ek cheez compensate kregi jiski wjh se net effect jo ki friction hai vo same ayega.
Pressure is a vector quantity. If you have time please check my statement . It is very crucial for all students of India. Imagine A rigid block I pushed it to 25 pa pressure and my friend pushes it 25 pa pressure in opposite direction Then if pressure is scalar net pressure on the block is 50 pa. Right But Now Imagine The block area is unit. Then I pushed it 25 N Force and my friend pushes it opposite -25N force Net force on the block is 0 then net pressure on the body is absolutely 0 pa But here is 50 pa how ???? Another example Let a inner point in a liquid the upward pressure + downward pressure +side pressure is 4hdg but net pressure is 0. As net force on the point is 0 so net pressure is 0 but if pressure is scale then it should be 4 hdg why it is not happens? My last example is related to biology In a kidney structure of a human body here is many nephrons. When ultra filtration process is happened in a nephron the net pressure is (effective filtration pressure) (Glomerular pressure - protein pressure - pressure of bowman's capsule ) It is subtraction of pressure direction wise not scalar addition . I think it that scientist do not want to reveal it as p=F/A All astonished about that a vector quantity is divided by a scalar quantity and resultant is vector So they expressed as scalar not really I think . Plz reply my comment . Dear sir
Ok so in your first explanation pressure is not zero . How?? So let's see , let's take a block which is very weak then if you and your friend will apply equal and opposite force then net force is zero but that force is creating pressure that's why it is deforming. So if pressure is zero then the box wouldn't crush but this is not true. Hence pressure is a scalar quantity.....
Bro you are right ! But mathematically p=F/A if F=0 then p=0 But pressure should be not non zero. But Our books calculate pressure by F/A . Plz answer my second question
