If the potential energy of a spring is V...

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

`V//25`

B

`5 V`

C

`V//5`

D

`25 V`

Text Solution

Verified by Experts

The correct Answer is:
D
`V = 1//2 K(2)^(2)`
`V' = 1//2 K(10)^(2)`
then `V' = 25 V`
