The system shown in th fig is released from rest. (Neglecting friction and mass of the pulley, string and spring). The spring can be elongated:

if `M gt m`

if `M gt 2m`

if `M gt m/2`

for any value of M (M should be greater than zero)

Text Solution

Verified by Experts

The correct Answer is:

Due to its own weight if `M ne 0`
