Blocks A and $C$ are connected with a rope, and Block $B$ is touching Block A but isnt attached to it$,$ as shown. If a person pushes Block $C$ to the right with a force of $25$ N $,$ what force will Block B exert on Block $A?m_A=m_C=8kg,m_B=3kg.$ lgnore frictional effects.

$($A$)10\mathrm{.}4$ N

B$)1\mathrm{.}3$ N

C$)9\mathrm{.}3$ N

D$)12\mathrm{.}7$ N

E$)3\mathrm{.}9$ N

The force diagram and numbers can be ignored. The only thing provided was the blocks diagram
