Answer 1

Answer:

An electron is projected with velocity v0 in a uniform electric field E perpendicular to the field. Again it is projected with velocity v0 perpendicular to a uniform magnetic field B. If r1 is initial radius of curvature just after entering in the electric field and r2in initial radius of curvature just after entering in magnetic field then the ratio r1 r2 is equal.
