Question

While the piston is at a distance 2 L from the top, the hole at the top is sealed. The piston is then released, to a position where it can stay in equilibrium. In this condition, the distance of the piston from the top is

Select the correct option:

A

$\left(\frac{2 \mathrm{P}_0 \pi \mathrm{R}^2}{\pi \mathrm{R}^2 \mathrm{P}_0+\mathrm{Mg}}\right)(2 \mathrm{~L})$

B

$\left(\frac{P_0 \pi R^2-M g}{\pi R^2 P_0}\right)(2 L)$

C

$\left(\frac{P_0 \pi R^2+M g}{\pi R^2 P_0}\right)(2 L)$

D

$\left(\frac{P_0 \pi R^2}{\pi R^2 P_0-M g}\right)(2 L)$
