Question: Crossed E and B Fields A particle with initial velocity V0 = (5.85 X 10' m/s)j enters a region of uniform electric and magnetic fields.

Crossed E and B Fields A particle with initial velocity V0 = (5.85 X 10' m/s)j enters a region of uniform electric and magnetic fields. The magnetic field in the region is B = - (1.35 T) k. Calculate the magnitude and direction of the electric field in the region if the particle is to pass through undeflected, for a particle of charge
(a) +0.640 nC and
(b) -0.320 nC. You can ignore the weight of the particle.
