A horizontal force $\displaystyle 10 N$ is applied to a block $\displaystyle A$ as shown in figure. The mass of blocks $\displaystyle A$ and $\displaystyle B$ are $\displaystyle 2$ kg and $\displaystyle 3$ kg , respectively. The blocks slide over a frictionless surface. The force exerted by block $\displaystyle A$ on block $\displaystyle B$ is :
