The value of Rydberg constant $\displaystyle \left(\mathrm{R}_{\mathrm{H}}\right)$ is $\displaystyle 2.18 \times 10^{-18} \mathrm{~J}$. The velocity of electron having mass $\displaystyle 9.1 \times 10^{-31} \mathrm{~kg}$ in Bohr's first orbit of hydrogen atom = $\displaystyle \_\_\_\_$ $\displaystyle \times 10^5 \mathrm{~ms}^{-1}$ (nearest integer).
