Question: A block of mass $\mathrm{M}$ is pulled along a horizontal frictionless surface by a rope of mass $\mathrm{m}$. If a force $\mathrm{P}$ is applied at the free end of the rope, the force exerted by the rope on the block is
$\frac{\mathrm{Pm}}{\mathrm{M}+\mathrm{m}}$
$\frac{\mathrm{Pm}}{\mathrm{M}-\mathrm{m}}$
$\mathrm{P}$
$\frac{\mathrm{PM}}{\mathrm{M}+\mathrm{m}}$
