Question:medium

Young's moduli of the material of wires A and B are in the ratio of 1:4, while its area of cross sections are in the ratio of 1:3. If the same amount of load is applied to both the wires, the amount of elongation produced in the wires A and B will be in the ratio of (Assume length of wires A and B are same)

Show Hint

When force and length are constant, elongation is inversely proportional to the product of area and Young's modulus ($ \Delta L \propto \frac{1}{AY} $). Just invert the given ratios and multiply them to get the answer quickly. \
