Solution

The correct option is D Acceleration of $m_{3}$ is zero
After cutting the string, force on $m_{4}$ changes, so it accelerates upwards. However, the springs are still expanded, so the tension in the springs remain the same. Therefore, at that instant, the blocks $m_{1}, m_{2}$ and $m_{3}$ are still at rest.

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 the acceleration of all the four blocks can be determined.
Statement III: Only

m_{4}

remains stationary.
Statement IV: Only

From the given system, just after cutting the string connecting m4 and ground, (here (m1+m2)>(m3+m4))

The correct option is D Acceleration of m3 is zeroAfter cutting the string, force on m4 changes, so it accelerates upwards. However, the springs are still expanded, so the tension in the springs remain the same. Therefore, at that instant, the blocks m1,m2 and m3 are still at rest.
