Question

A block of mass M is pulled along a smooth horizontal surface with a rope of mass m by force F. The acceleration of the block will be, F M - m, F M + m, F m, F M

MARKS App · Accepted Answer

When a block of mass m is pulled along smooth horizontal surface with rope of mass m by force F, then (M + m) will be the total mass of the system. ∴ F = M + m a ⇒ a = F M + m
