Find the mass m in the figure for the system to be at rest

Masses m_(1), m_(2), m_(3) and m_(4) are arranged in a system as shown in fig where m_(1) +m_(2) gt m_(3)+m_(4) The lower string keeping the system in equilibrium is burnt The masses start moving. Find the acceleration of masses if the threads are weightless and inextensible the springs are also weightless and the mass of the pulley is negligible.

For the system shown in fog. m_(1) gt m_(2) gtm_(3) gt m_(4) . Initially, the system is at rest in equilibrium condition., if the string joining m_(4) and ground is cut, then just after the string is cut. Statement I: m_(1), m_(2), m_(3) remain stationary. Statement II: The value of acceleration of all the four blocks can be determined. Statement III: Only m_(4) remain stationary. Statement IV: Only m_(4) accelerates.

In the arrangement shown in the figure (m_(A))/(m_(B))=(2)/(3) and the ratio of density of block B and the liquid is 2:1 The system is released from rest. Then
