In Bohr's atomic model, the electron is assumed to revolve in a circular orbit of radius $\displaystyle 0.5 \AA$. If the speed of electron is $\displaystyle 2.2 \times 10^6 \mathrm{~m} / \mathrm{s}$, then the current associated with the electron will be \_\_\_\_ $\displaystyle \times 10^{-2} \mathrm{~mA}$. [Take $\displaystyle \pi$ as $\displaystyle \frac{22}{7}$ ]
