A simple pendulum made of a bob of mass $\displaystyle m$ and a metallic wire of negligible mass has time period $\displaystyle 2$ s at $\displaystyle T=0^{\circ} \mathrm{C}$. If the temperature of the wire is increased and the corresponding change in its time period is plotted against its temperature, the resulting graph is a line of slope $\displaystyle S$. If the coefficient of linear expansion of metal is $\displaystyle \alpha$ then the value of $\displaystyle S$ is :
Official answer
(1)
$\displaystyle \alpha$
