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