Question 1 Report

Two metals P and Q are heated through the same temperature difference. If the ratio of the linear expansivities of P to Q is 2:3 and the ratio of their

Length is 3: 4 respectively, the ratio of the increase in lengths of P to Q is

1:2

2:1

8:9

9:8

Answer Details

P: $\frac{α h θ}{α h θ}$

$\frac{2 \times 3 \times θ}{3 \times 4 \times θ}$

$\frac{1}{2}$
