Question

The give graph shown variation (with distance r from centre) of :
(A) Electric field of a uniformly charged sphere (B) Potential of a uniformly charged spherical shell (C) Potential of a uniformly charged sphere (D) Electric field of a uniformly charged spherical shell

Answer 1

Answer:

(B) Potential of a uniformly charged spherical shell

Explanation:

When r < r0. ( inside ). V = K × Q / r0. Since r0 ( radius of circle ) is fixed, it gives a constant value .

When r > r0. ( outside ). V = K × Q / r. Here r is not constant . V varies inversely with r.

Therefore, in the graph first it gives constant value then varies inversely with r.
