Elastic Modulie

Question

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 the two wires will be

Moderate

A

1 : 2
B

1 : 4
C

2 : 1
D

1 : 1

Solution

$W = \frac{1}{2} Fl ∴ W \propto l (F is constant)$
$∴ \frac{W_{1}}{W_{2}} = \frac{l_{1}}{l_{2}} = \frac{l}{2 l} = \frac{1}{2}$
