A) \[2\pi RF\]
B) \[2RF\]
C) \[RF\]
D) \[zero\]
Correct Answer: D
Solution :
Key Idea: Work done\[(W)\]=Force\[(F)\]\[\times \]displacement\[(d)\] For a body rotating in circular motion, centripetal force is directed towards the centre of the circle when body completes one rotation, its displacement is zero, hence Work done \[=\] force \[\times \] displacement \[W=F\times 0=0\]You need to login to perform this action.
