Gravitational Potential

A particle of mass is situated at the centre of a spherical shell of the same mass and radius The gravitational potential at a point situated at distance from the centre, will be:
1.
2.
3.
4.

An infinite number of bodies, each of mass are situated on the axis at distances respectively, from the origin. The resulting gravitational potential due to this system at the origin will be:

1.		2.
3.		4.

Match List-I with List-II.
