Question

Block A is kept on top of block B and moves leftwards with respect to B. Assume the friction to be present between the blocks. The direction of friction force on A by B, will be?

Options:

A . → (Rightwards)

B . ←(Leftwards)

C . ↘

D . ↙

Answer: Option A
:
A
Block A moves in the leftward direction with respect to B. ∴ Friction will act in the rightward direction on A. As the bonds formed will oppose the relative motion.
