A disc is pulled by a force F acting at ...

A disc is pulled by a force `F` acting at a point above the centre of mass of the disc.
The direction of frictional force `(f_r)` acting on disc pushed on a rough surface will be represented by.

A

.

B

.

C

.

D

Information is insufficient.

Text Solution

Verified by Experts

The correct Answer is:
B
(b) As `K^2 lt Rx`
Here `K^2 = (R^2)/(2), x = R`
Hence friction will act in forward direction.'
