The kinetic energy of an electron in the second Bohr orbit of a hydrogen atom is equal to $\displaystyle \frac{\mathrm{h}^2}{x \mathrm{~m} \mathrm{a}_0^2}$. The value of $\displaystyle 10 x$ is \_\_\_\_. ( $\displaystyle \mathrm{a}_0$ is radius of Bohr's orbit) (Nearest integer) [ Given : $\displaystyle \pi=3.14$ ]
