In the figure small block is kept on m then

Options

  1. Athe acceleration of m w.r.t. ground is F m
  2. Bthe acceleration of m w.r.t. ground is zero
  3. Cthe time taken by m to separate from M is 2 m F
  4. Dthe time taken by m to separate from M is 2 C M F

Correct answer

D. the time taken by m to separate from M is 2 C M F

Step-by-step solution

Acceleration of M, a= ( F M ) = 1 2 F M t ^2 t = 2 M F
