An electron is released from a distance of 4 m from a stationary point charge 20 nC . What will be the speed of the electron, when it is
2 m away from the point charge?
(Charge of electron $=1.6 \times 10^{-19} \mathrm{C}$, mass of electron
\(=9 \times 10^{-31} \mathrm{~kg}, \frac{1}{4 \pi \varepsilon_0}=9 \times 10^9 \text { SI unit) }\)
