Physics - Electrostatics Question with Solution | TestHub

An electron revolves around an infinite cylindrical wire having uniform linear charge density $2\times 10^{-8}C{m}^{-1}$ in circular path under the influence of attractive electrostatic field as shown in the figure. The velocity of electron with which it is revolving is $\_\_\_\_$ $\times 10^{6}m{s}^{-1}$. Given mass of electron $=9\times 10^{-31}kg$.
