Question

A fixed volume of iron Is drawn into a wire of length L The extension X produce in the wire by a constant force F is proportional to

Answer 1

Answer:

$L^{2}$

Explanation:

Y = = (FL / Ax)

extension x = (FL / AY) = [{F$L^{2}$} / {(AL)Y}]    .......(1)

volume = V = Area × length  i.e. V = AL

x = (F$L^{2}$/ VY)

F is given to be constant, Y is constant.

If volume is fixed then x ∝ L2
