In the Figure, the ball A is released from rest when the spring is at its natural length. For the block B of mass M to leave contact with the ground of some stage, the minimum mass of A must be :
  • a)
    2M
  • b)
    M/4
  • c)
    M/2
  • d)
    M
Correct answer is option 'C'. Can you explain this answer?
