A wire suspended vertically from one of ...

A wire suspended vertically from one of itsends is strached by attached a weight of `200 N` to the lower end . The weight streches the wire by `1 mm` . Then the elastic energy stored in the wire is

A

`0.2 J`

B

`10 J`

C

`20 J`

D

`0.1 J`

Text Solution

Verified by Experts

The correct Answer is:
D
The elastic potential energy
` = (1)/(2) xx force xx extension = (1)/(2) xx 200 xx 0.001 = 0.1 J .`
