Q.  What is the gravitational potential energy for infinite distance?

a. 0
b. infinity
c. 9.8 J
d. None of the above


ANSWER: See Answer
 
The gravitational potential energy of a body at a point is defined as the amount of work done in bringing the body from infinity to that point against the gravitational force. U = – GMm/r When r =infinity, then U =0
