Question

A long spring when stretched by 10 cm has potential energy u

Answer 1

yes potential energy is the right answer because for potential energy is because of its specific state or position

Answer 2

Answer:

Explanation:

We know, potential energy of spring is given by (1/2)kx² where k is spring constant and x is stretched distance.

Here , x=2cm so, U=(1/2)k*2²=2k

For, x=10cm :-

E=(1/2)k*10²=50k=25(2k)=25U.

Final potential energy will be 25U.
