Q. Let and be the gravitational potential and gravitational field. Then select the correct alternative(s) :

Gravitation Report Error

The plot of against (distance from centre) is discontinuous for a spherical shell

The plot of against is continuous for a spherical shell

The plot of against is discontinuous for a solid sphere

The plot of against is continuous for a solid sphere

Solution:

For a spherical shell inside but constant and outside both are non zero hence options (A) and (B) are correct. For a solid sphere inside and both are non zero and varies continuously with distance from inside to outside hence option (D) is correct.
