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

Options

  1. AF M - m
  2. BF M + m
  3. CF m
  4. DF M

Correct answer

B. F M + m

Step-by-step solution

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
