Laws of Motion

A horizontal force of 10 N is applied to a block A, which is in contact with a block B on the side away from the force. The masses of blocks A and B are 2 kg and 3 kg respectively. The blocks slide over a frictionless surface. The force exerted by block A on block B is:

  1. A.4 N
  2. B.6 N✓
  3. C.10 N
  4. D.Zero

Solution

Both blocks share acceleration . The only horizontal force on B is the push from A: N.
