28 A system of blocks A and B of masses m and m2 connected by a spring of force constant k is placed on a spring of force constant k which rests on the ground Both the springs are vertical and the whole system is in equilibrium Find increment in gravitational potential energy of the system in lifting the block A upwards until the lower spring becomes relaxed B F k
