Mercury is filled in a tube of radius $\displaystyle 2$ cm up to a height of $\displaystyle 30$ cm . The force exerted by mercury on the bottom of the tube is $\displaystyle \_\_\_\_$ $\displaystyle N$. (Given, atmospheric pressure $\displaystyle =10^5 \mathrm{Nm}^{-2}$, density of mercury $\displaystyle =1.36 \times 10^4 \mathrm{~kg} \mathrm{~m}^{-3}, g=10 m s^{-2}, \pi=\frac{22}{7}$ )
