140891 Two wires are made of the same material and have the same volume. However wire 1 has cross-sectional area $A$ and wire 2 has crosssectional area $3 \mathrm{~A}$. If the length of wire 1 increases by $\Delta x$ on applying force $F$, how much force is needed to stretch wire 2 by the same amount?
