Two wires A and B of same length, same area of cross-section having the same Young's modulus are heated to the same range of temperature. If the coefficient of linear expansion of A is 3/2 times of that of wire B. The ratio of the forces produced in two wires will be
Text Solution
Verified by ExpertsThe correct answer is:
D
$F = Y A \alpha \Delta \theta$
If Y, A and Δ Δ θ θ are constant then $\frac{F_{A}}{F_{B}} = \frac{\alpha_{A}}{\alpha_{B}} = \frac{3}{2}$
