A yo-yo is placed on a rough horizontal ...

A yo-yo is placed on a rough horizontal surface and a constant force `F`, which is less than its weight, pulls it vertically. Due to this

A

friction force acts towards left, so it will move towards left

B

friction force acts towards right, so it will move towards right

C

it will move towards left, so friction force acts towards left

D

it will move towards right so friction force acts towards right

Text Solution

Verified by Experts

The correct Answer is:
A
`F` will provide anticlockwise torque about the centre due to which the bottomost point will tend to move towards right, so friction will act towards left. So it will move towards left.
