of of same mass and radius a The gravitational lpotentialat the
point situated at a/2 distance from the centerwill be

Aditi · Accepted Answer

The gravitational potential at the point P due to the particle at the centre is V1 = – GM  a/2 =-2GM a The potential at P due to the shell is ,V2 = -GMa The net potential at P is V1 + V2 = – 3GM a
