I would definitely say at this point Calculus 3 would be very useful, and he maybe skipped a couple steps when discussing Gaussian surfaces assuming you would understand what he meant by choosing what the surface should be. Also, I think the flux explanation leading into Gauss's law needed a little more to it. As for symmetry, it would be helpful once you've worked through the math to follow a textbook and do the examples and view online solutions.
@l.fsader60215 жыл бұрын
don't over due the learning curve. you need to fully understand trig and algebra to understand what he means by symmetry. The radius is the same distance along the surface of the circle with radius r. because of this it does not matter where on the surface you relate the electric field to AS LONG as the charge is uniformly spread on the surface. This is because a sphere's surface is the same distance to the origin with respect to whatever radius you assign it.

Does Earnshaw's theorem have any application here? The second thing, while touching the above end of Electrophorus to transfer the negative charge to the earth, were you wearing shoes? Then how do the charges move to the ground? I will be pleased if you answer these doubts. Respect and Love from India.

Ok sir, I think i got it. If no charge, no field lines are coming in or going out. If charge is outside then the number of lines coming in is equal to number of lines going out, so no net flux and no net E field. Correct me sir if i am wrong anywhere.

@@adokapo you can look it up on KZbin there are many tutorials on how to do it. Its basically depending on the angle between the board and the chalk

I don't think it is possible to make a circle with that trick, the angle of the chalk with the board must remain constant.

Sir why didn't you explain that why flux through an outside charge is zero.. i came for that only. 😂😂

Because by the sign convention flux entered is taken positive and flux gone out is taken as negative so the net flux is taken 0

Woow ... What is so difficult to my lecture to illustrate this...coz Theoreticaly it's hard to understand all these with dimensions and drawings, only practically will save the lecture🙏❤️ Thank you Sir

Hello Sir, what would be the position of charges if a closed conductor having a cavity is placed in uniform electric field?
@lecturesbywalterlewin.they92595 жыл бұрын
the net charge on the conductor will be zero. charge density at the surface (both + and --) will depend on geometry. The conductor will be an equipotential everywhere - at its surface, inside the conductor and inside the cavity.

You dedicated the real but hardly-achieved joy of science to the world and that's a great service. Thank you very much sir. Professor, I have a question. The infinite plane you calculated the electric field for, was a non-conductor one?
