The potential energy stored in a certain spring when stretched through `10cm` is `5J`. The amount of work that must be done to stretch it (slowly) through an additional distance of `10cm` is

The potential energy of a certain spring when stretched through a distance 'S' is 10 joule. The amount of work (in joule) that must be done on this spring to stretch it through an additional distance 'S' will be

The PE of a certain spring when streched from natural length through a distance 0.3m is 5.6J . Find the amount of work in joule that must be done on this spring to stretch it through an additional distance 0.15m .

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 man carries a load on his head through a distance of 5 m. The maximum amount of work is done when he

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

A man carries a load of 5 kg on his head through a distance of 10 m. the minimum amount of work is done when he

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

A spring requires 4 Joule of work to be stretched through 10 cm. Find the spring constant.

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
