Physics - Elasticity Question with Solution | TestHub

Two separate wires$A$and$B$are stretched by$2 \mathrm{mm}$and$4 \mathrm{mm}$respectively, when they are subjected to a force of$2 \mathrm{N}.$Assume that both the wires are made up of same material and the radius of wire$B$is$4$times that of the radius of wire$A.$The length of the wires$A$and$B$are in the ratio of$a: b.$Then$\frac{a}{b}$can be expressed as$\frac{1}{x}$, where$x$is _____.
