An electron (mass =9.1xx10^(-31)kg , charge =1.6xx10^(-19)C ) experiences no deflection if subjected to an electric field of 3.2 x 10^(5)V/m , and a magnetic fields of 2.0xx10^(-3)Wb/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
