The temperature of a thin uniform rod increases by

\Delta t

. If moment of inertia I about an axis perpendicular to its length then its moment of inertia increases by

View answer and explanation

Correct option: C

2\alpha I\,\Delta t

Option C (

2\alpha I\,\Delta t

) is correct because the moment of inertia increases proportionally to the square of the length, and the length increases linearly with temperature.
