A U shaped container has uniform cross sectional area S. It is suspended vertically with the help of a spring and two strings A and B as shown in the figure. The spring and strings are light. When water (density = d ) is poured slowly into the container it was observed that the level of water remained unchanged with respect to the ground. Find the force constant of the spring.

System shown in fig is in equilibrium and at rest. The spring and string are massless now the string is cut. The acceleration of mass 2m and m just after the string is cut will be:

In the figure a mass m is hung by a light spring and a light string as shown .Both the spring and the string make an angle theta with the horizontal at equilbrium .If the string is suddenly cut then the instantaneous acceleration of the mass m is :

The system shown in the following figure is in equilibrium and at rest. The spring and string are massless. Now, the string is cut. The acceleration of mass 2m and m, just after the string is cut, will be
