In the system shown in figure, the two springs `S_(1) "and" S_(2)` have force constant k each. Pulley, springs and strings are all massless. Initially, the system is in equilibrium with spring `S_(1)` stretched and `S_(2)` relaxed. The end A of the string is pulled down slowly through a distance L. By what distance does the block of mass M move?

The fig. shows an infinite tower of identical springs each having force constant k. The connecting bars and all springs are massless. All springs are relaxed and the bottom row of springs is fixed to horizontal ground. The free end of the top spring is pulled up with a constant force F. In equilibrium, find (a) The displacement of free end A of the top spring from relaxed position. (b) The displacement of the top bar B1 from the initial relaxed position.

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:

There are two identical spring each of spring constant k. here springs, pulley and rods are massless and the block has mass m . What is the extension of each spring at equilibrium?
