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

A

`(u)/(5)`

B

5u

C

10u

D

25u

Text Solution

Verified by Experts

The correct Answer is:
d
`(E_(2))/(E_(1))=(1/2k(10)^(2))/(1/2k(2)^(2))=25`
` implies E_(2)=25 E_(1)`
