Question

a string is wrapped around a cylinder of radius R and pulled at the topmost horizontal by force F. the cylinder rolls without spilling on the horizontal surface. the work done by the force by the time the cylinder makes one full rotation is. ​

Answer 1

Answer:

C

Explanation:

Answer 2

Answer: F.2πR

Explanation:
Work done = F.S ans S is the displacement which here equal to 2πR.
Therefore Work done = F.2πR
