Answer Key / Explanation : (b) -

(b)

Solve to get

, if

if

So friction will act in the forward direction

if  so friction will act in the backward direction. Also solved to get

is positive for all cases, hence body will accelerate in the forward direction in all cases

It means  will be in the clockwise direction. Hence, bodies will rotate in the clockwise direction
