WebDec 9, 2024 · Let a point charge + Q is placed in center of hollow spherical conductor of inner radius a and outer surface b. Then the charge on the inner surface of radius a is − Q and outermost surface has charge + Q (using E = 0 in conductor and Gauss' theorem). WebHowever, the electric field in the hollow part has not spherical symmetry anymore, and therefore, the Gauss law is not useful to find the field there. In the hollow region, we have to calculate the electric potential first, and then take its gradient. The electric potential in the hollow can be calculated by using the method of images.

WebSTEP 1 - Choosing a Gaussian surface Now that we know what the electric field looks like everywhere, choose a Gaussian surface that would make calculating the electric flux, easy. What closed surface would you choose here? Choose 1 answer: Concentric sphere of … WebGravitational potential of a spherical shell at a point inside is given by V p = − G M R As the shell is compressed to half its radius the mass will still remain same. The new potential will be V ′ p = − G M (R 2) = − 2 G M R Thus, due to the negative sign, when the radius is halved the potential decreases. Hence, option (b) is the ...
