Two wires are made of same material and have the same volume. However wire 1 has cross-sectional area A and wire 2 has cross-sectional area 3A. If the length of wire 1 increases by ∆x on applying force F, how much force is needed to stretch wire 2 by the same amount F 4F 6F 9F

Since both the wires are made from the same material therefore Young's Modulus for both will be same,i.e.,

Y1 = Y2.

Use this comcept and you will get answer as 9F
