Let V and E be the gravitational potential and gravitational field at a distance r from the Centre of a uniform spherical shell. Consider the following two statements:

(A)The plot of V against r is discontinuous

(B)The plot of E against r is discontinuous

A. Both A and B are correct.

B. A is correct but B is wrong.

C. B is correct but A is wrong.

D. Both A and B are Wrong C.

Answer :

Here, (a) is false as V is constant inside a spherical shell and is equal to where a is the radius of the shell, after which it decreases to zero as . Option (b) is true as the electric field inside a shell is zero but just outside the shell, its which decreases to zero as .
