A wheel of radius `R` has an axle of radius `R//5`. A force `F` is applied tangentially to the wheel. To keep the system in a state of "rotational" rest, a force `F'` is applied tangentially to the axle. The value of `F'` is

A

F

B

3F

C

5F

D

7F

Text Solution

Verified by Experts

The correct Answer is:
C
`F' xx R/5 = FR` or `F' = 5F`
