Question:medium
A bar magnet has a period of oscillation $T$. If a similar brass piece of the same mass is placed over it, then the number of oscillations it makes in one second is
A bar magnet has a period of oscillation $T$. If a similar brass piece of the same mass is placed over it, then the number of oscillations it makes in one second is
Show Hint
Frequency $\propto \frac{1}{\sqrt{I}}$ → more inertia = slower oscillation.
