Solution

The correct option is B Friction will act in the backward direction
A ring of mass kept on a horizontal rough A force F is applied tangentially at its rim as shown. The coefficient of frictionless between the ring and the surface is μ Then friction will act in the backward direction.
so the correct option is B.
