Q. Identify the correct definition of gravitational potential at a point.

Gravitation Report Error

A

it is defined in terms of the force required to displace a unit mass from infinity to that point

25%

B

it is defined in terms of the force required to move a unit mass from the surface of earth to that point

0%

C

it is defined in terms of the force required to displace a unit mass from that point to infinity

0%

D

none of these

75%

Solution:

In all the options given, the term force is used. But gravitational potential at a point is defined in terms of the work done in displacing a unit mass from infinity to that point without change in kinetic energy.
