A body of mass 2 kg is moved from a point A to a point B by an external agent in a conservative force field. If the velocity of the body at the points A and B are 5 m/s and 3 m/s respectively and the work done by the external agent is –10 J, then the change in potential energy between points A and B is
- 6 J
- 36 J
- 16 J
- none of these
Answer
(A) 6 J
