When the load on a wire is slowly increased from `3kgwt` to `5 kg wt`, the elongation increases from `0.61` to `1.02 mm`. The work done during the extension of wire is

A

16 J

B

1.6 J

C

0.16 J

D

0.016 J

Text Solution

Verified by Experts

The correct Answer is:
D
`W = W_(2) - W_(1) = (1)/(2) [M_(2)gl_(2) - M_(1)gl_(1)] = 0.016 J`
