Strain in wire is .01

Boss… here is the procedure of solving the prob.

Strain = change in length

———————–

total length

Let the initial length of the wire be L.

Then final length = initial length + increased length

= L + L * (1/100)

= (101* L) /100

Change in length = final length – initial length

= [(101 * L)/100] – L

= L/100

Strain = [L/100] / L

= 1/100

= 0.01 Ans. ðŸ™‚
