A ring of mass m and radius R rolls on a...

A ring of mass `m` and radius `R` rolls on a horizontal roudh surface without slipping due to an applied force `'F'`. The frcition force acting on ring is `:-`

A

`(F)/(3)`

B

`(2F)/(3)`

C

`(F)/(4)`

D

Zero

Text Solution

Verified by Experts

The correct Answer is:
D
`(D)F+f=ma .....(1)`
Also `, FR-fR=I(a)/(R)`
`F-f=ma ….(2)`
`[I=mR^(2)]`
From `(1) & (2)`
`f=0`
