4 49 An electron is projected with velocity vo in a uniform electric field E perpendicular to the field Again it is projected with velocity vo perpendicular to a uniform magnetic field B If r is initial radius of curvature just after entering in the electric field and r is initial radius of curvature just after entering in magnetic field then the ratio r r is equal to
