   A horizontal force 10 N is applied to a block A as shown in figure. The mass 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: Block A (2 kg) is pushed by $F = 10$ N towards the right and is in contact with block B (3 kg) on its right side; both rest on a frictionless horizontal surface.

   • (A)
     zero

     6 N
   • (D)
     10 N
