A wire of length 3.0m has a percentage strain of `0.015%` under a tensile force.Determine the extension in the wire.

A

0.60 mm

B

0.45 mm

C

0.75 mm

D

0.90 mm

Text Solution

Verified by Experts

The correct Answer is:
B
Here, original length, `l=3.0m`
Strain ,`Delta l = (0.015)/(100)l = (0.015 xx 3.0)/(10)`
`=0.45 xx 10^(-3) m`
`=0.45 mm` .
