A wire whose cross-sectional area is `4mm^(2)` is streched by `0.1mm` by a certain load. If a similar wire of double the area of cross-section is under the same load, then the elongation would be

A

`0.5mm`

B

`0.05mm`

C

`0.005mm`

D

`5mm`

Text Solution

Verified by Experts

The correct Answer is:
