The PE of a long spring when stretched by 3cm is U .If the spring is stretched by 6cm the PE will be

The potential energy of a long spring when stretched by 2 cm is U. If the spring is stretched by 8 cm the potential energy stored in it is:-

A long elastic spring is stretched by 2 cm and its potential energy is U . If the spring is stretched by 10 cm , the PE will be

When a long spring is stretched by 2 cm, its potential energy is V. If the spring is stretched by 10 cm, the potential energy in it will be

A long spring is stretched by 3 cm and its potential energy is V . If the spring is stretched by 6 cm ,its potential energy will be

A long spring is stretched by 2 cm, its potential energy is U. IF the spring is stretched by 10 cm, the potential energy stored in it will be

A long spring is stretched by 2 cm and the potential energy is V. IF the spring is stretched by 19 cm, its potential energy will be

When a spring is stretched by 2 cm, it stores 100J of energy. If it is further stretched by 2 cm, the increase in energy is

Potential energy of an ideal spring, when stretched by 1 cm is U. Spring is now cut in two equal parts and connected in parallel. If the new combination of spring is compressed by 2 cm, then potential energy stored is

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 :

If the potential energy of a spring is V on stretching it by 2cm , then its potential energy when it is stretched by 10cm will be
