In an experiment, electrons are accelerated, from rest, by applying a voltage of $\displaystyle 500$ V. Calculate the radius of the path if a magnetic field $\displaystyle 100$ mT is then applied. [Charge of the electron $\displaystyle =1.6 \times 10^{-19} \mathrm{C}$ Mass of the electron $\displaystyle =9.1 \times 10^{-31} \mathrm{~kg}$ ]
