→An electron $($mass $= 9.1 \times 10^{-19} \mathrm{~kg} ;$ charge $=1.6 \times 10^{-19} C)$ experiences no deflection if subjected to an electric field of $3.2 \times 10^5 \mathrm{V} / \mathrm{m},$ and a magnetic fields of $2.0 \times 10^{-3}\ \mathrm{Wb} / \mathrm{m}^2.$ Both the fields are normal to the path of electron and to each other. If the electric field is removed, then the electron will revolve in an orbit of radius
