Question

A steel wire is suspended vertically from a rigid support. When loaded with a weight in air, it extends by $l_{a}$ and when the weight is immersed completely in water, the extension is reduced to $l_{w}$. Then the relative density of material of the weight is(a) $\frac{l_{a}}{l_{w}}$(b) $\frac{l_{a}}{l_{a}-l_{w}}$(c) $\frac{l_{w}}{(l_{a}-l_{w})}$(d) $\frac{l_{w}}{l_{a}}$
