A block of mass M is pulled along a horizontal frictionless surface by a rope of mass \( \mathrm{m} \). If a force \( \mathrm{F} \) is applied at one end of the rope, the force which the rope exerts on the block is :-
(1) \( F /(M+m) \)
(2) \( \mathrm{F} \)
(3) \( F M /(m+M) \)
(4) Zero
\( \mathrm{P} \)
