Block A is kept on block B as shown in figure. It is known that acceleration of block A is `2 m//s^(2)` towards right and acceleration of block B is `3 m//s^(2)` towards right under the effect of unknown forces. Direction of friction force acting on A by B `(mu_(AB) = 0.3)`

A

is necessarily towards right

B

may be towards right

C

may be towards left

D

may be zero

Text Solution

Verified by Experts

The correct Answer is:
B, C, D
B.C.D direction of friction do not depend on direction of force but it depends on direction of relative motion (velocity)
