Q- A charged particle (q = +3.5 µC) moves at speed v0 = 55 m/s in the +x-direction. At x = 0 it enters a region where a uniform magnetic field B = 2.5 T directed in the +z direction.
(a) What is the magnitude of the magnetic force on the particle?
(b) What electric field can make the net force on the particle equal to zero?
(c) If the incoming particle were replaced by one with the opposite electric charge but the same initial velocity, what electric field would be required to ensure a straight line motion? (Magnetic field is unchanged.)
