A particle of charge +q and mass m moving under the influence of a uniform electric field E cap i and a magnetic field B cap k enters in I quadrant of a coordinate system at a point (0, a) with initial velocity v cap i and leaves the quadrant at a point (2a, 0) with velocity = -2v cap j . Find Magnitude of electric field
(a) Rate of work done by the electric field at point
(b) (0, a) Rate of work done by both the fields at.
(c) (2a, 0)
