In Bohr’s atomic model, the electron is assumed to revolve in a circular orbit of radius 0.5 A. If the speed of electron is ${\mathrm{2.2\times 10}}^{\mathrm{6}}\hspace{0.17em}\mathrm{m}/\mathrm{s}$ , then the current associated with the electron will be  ${\text{×10}}^{-2}\text{\hspace{0.17em}mA.[Take \hspace{0.17em}}\mathrm{\pi }\text{\hspace{0.17em}\hspace{0.17em}as \hspace{0.17em}}\frac{22}{7}]$___
