Question

On a smooth plane surface (figure) two block A and B are accelerated rightwards by applying a force 15 N on A . If the mass of B is twice that of A , the force on B is, 30 N, 15 N, 10 N, 5 N

MARKS App · Accepted Answer

The acceleration of both the blocks = 15 3 x = 5 x ∴ Force on B = 5 x × 2 x = 10 N
