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 :
Answer: (A) $6$ N
Concept. Both blocks share one acceleration; the push from A is the only horizontal force on B.
Step 1. Acceleration. $a = \dfrac{10}{5} = 2\ \text{m s}^{-2}$.
Step 2. Contact force. $3 \times 2 = 6$ N.
Answer. $6$ N (Option A).
