Question 15 of 116

Coefficient of linear expansion of brass and steel rods are $α_{1} a n d α_{2},$ Lengths of brass and steel rods $l_{1} a n d l_{2}$ respectively. If $(l_{2} - l_{1})$ is maintained same at all temperatures, Which one of the following relations holds good?

(a) $α_{1} l_{2}^{2} = α_{2} l_{1}^{2}$ (b) $α_{1}^{2} l_{2} = α_{2}^{2} l_{1}$

(c) $α_{1} l_{1} = α_{2} l_{2}$ (c) $α_{1} l_{2} = α_{2} l_{1}$
