Q. In which of the following cases, can the work done increase the potential energy?
A) Both conservative and non-conservative forces
B) Conservative force only
C) Non- conservative force only
D) Neither conservative nor conservative forces
Explanation
(b) In case of non-conservative forces, the work done is dissipated as heat, sound etc. $ie$, it does not increase the potential energy. But in case of conservative forces, work done is responsible for increasing the potential energy
