When a 20 g mass hangs attached to one end of a light spring of length 10 cm, the spring stretches by 2 cm. The mass is pulled down until the total length of the spring is 14 cm. The elastic energy, (in Joule) stored in the spring is :

When a 1.0kg mass hangs attached to a spring of length 50 cm, the spring stretches by 2 cm. The mass is pulled down until the length of the spring becomes 60 cm. What is the amount of elastic energy stored in the spring in this condition. if g = 10 m//s^(2).

When a 1 kg mass is hung from a spring 50 em long, it stretches by 2 cm. The mass is then pulled down until the length of spring becomes 60 cm. The amount of clastic energy stored in the spring in this condition when g is 10 ms^(-1) can be given as

A long spring is stretched by 2 cm having potential energy as V. If the spring is stretched by 10 cm, the potential energy would be

When a spring is stretched by 10 cm, the potential energy stored is E. When the spring is stretched by 10 cm more, the potential energy stored in the spring becomes

When a spring is stretched by 10 cm, the potential energy stored is E. When the spring is stretched by 10 cm more, the potential energy stored in the spring becomes

When a spring is stretched by 10 cm, the potential energy stored is E. When the spring is stretched by 10 cm more, the potential energy stored in the spring becomes

A massless spring of natural length of 0.5 m and spring constant 50 N/m has one end fixed and the other end attached to a mass of 250 g. The spring mass system is on a smooth floor. The mass is pulled until the length of the spring is 0.6 m and then released from rest. The kinetic energy of the mass when the length of the spring is 0.5 m is
