Examine these two statements and and select the answer:
Statement I : A body moving in a circular path is acted upon by the centripetal force.
Statement II : Centripetal force acting on the body is doing work to keep it rotating in the circular path.

Both the statements are individually true and Statement II is the correct explanation of Statement I

Solution

The correct option is C Statement I is true but Statement II is false
Centripetal force is applied perpendicular to the motion of the body. Since, dW = F.ds
hence the work done by this force is "0". which proves that sta. 2 is wrong.
while sta. 1 is a fact
Hence,
C is the answer.
