Physics - NLM Question with Solution | TestHub

The acceleration of the system (block + rope) is

$a=\frac{P}{M+m}$.

The force exerted by the rope on the block is $F=Ma$.

Substituting the expression for $a$, we get $F=M\cdot \frac{P}{M+m}=\frac{MP}{M+m}$.

Therefore, the force exerted by the rope on the block is $\frac{MP}{M+m}$.
