Question

Block 'A' is placed over the block 'B' as shown in the figure. Wedge is fixed and there is no friction. Between block 'B' and fixed inclined. Force of friction on the block 'A' is :

(A) towards right

(B) towards left

(C) zero 

(D) always kinetic 

Answer 1

Correct option- (B) towards left

Explanation:-

The tendency of relative motion along the tangent plane between 'A' and 'B' blocks will be due to the motion of block 'B' along the fixed inclined plane
