Two cylindrical vessels of equal cross-sectional area $\displaystyle 16 \mathrm{~cm}^2$ contain water upto heights $\displaystyle 100$ cm and $\displaystyle 150$ cm respectively. The vessels are interconnected so that the water levels in them become equal. The work done by the force of gravity during the process, is [Take, density of water $\displaystyle =10^3 \mathrm{~kg} / \mathrm{m}^3$ and $\displaystyle \mathrm{g}=10 \mathrm{~ms}^{-2}$ ]:
Official answer
(2)
$\displaystyle 1$ J
