Question

What amount of work is done in increasing the length of a wire through unity?

Options:

A . YL2A

B . YL22A

C . YA2L

D . YLA

Answer: Option C
:
C
Work done

= \frac{1}{2} F \times

extension

= \frac{1}{2} \times \frac{Y A}{L} \times 1 y = \frac{F \times L}{A \times 1}

= \frac{Y A}{2 L} h e n c e F = \frac{Y A}{2 L}
