Consider a region with uniform electric field and uniform magnetic field which are mutually perpendicular.Their magnitudes are 1.0 ~V . m ⁻¹ and 0.1 T , respectively. A charged particle of mass 1.0 gram enters this region with a velocity perpendicular to the electric field. The particle moves with a constant velocity making an angle of 45^ with the magnetic field. Neglecting gravity, the kinetic energy of the particl
