Two wires of same diameter of the same material having the length `l` and `2l` If the force `F` is applied on each, the ratio of the work done in two wires will be

A

`1 : 2`

B

`1 : 4`

C

`2 : 1`

D

`1 : 1`

Text Solution

Verified by Experts

The correct Answer is:

a

`W = (1)/(2) F I`
`:. W prop I`
`:. (W_(1))/(W_(2)) = (I_(1))/(I_(2)) = (I)/(2I) = (1)/(2)`
