Q. A uniform metal rod of length 'L' and mass 'M' is rotating about an axis passing through one of the ends perpendicular to the rod with angular speed $'\omega'.$ If the temperature increases by $''t^\circ\,C''$ then the change in its angular velocity is proportional to which of the following ? (Coefficient o f linear expansion of rod = $\alpha$ )

Solution:

Correct answer is (b) $\omega$
