    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. 🙂
