A hydrometer executes simple harmonic motion when it is pushed down vertically in a liquid of density $$\rho$$. If the mass of hydrometer is $$m$$ and the radius of the hydrometer tube is $$r$$, then the time period of oscillation is

$$T=2 \pi \sqrt{\frac{m}{\pi^2 \rho g}}$$

$$T=2 \pi \sqrt{\frac{\pi \pi^2 \rho g}{m}}$$

$$T=\frac{1}{2 \pi} \sqrt{\frac{m}{\pi \pi^2 \rho g}}$$

$$T=\frac{1}{2 \pi} \sqrt{\frac{\pi \pi^2 \rho g}{m}}$$
