a positive charge (q= 3x10^-6C) moves at constant velocity of 50m/s between two parallel plates as shown. the parallel plates result in a uniform electric field between the plates of 210 V/m. a magnetic field is set up between the plates so that the charge passes through the plates undeflected.

a- sketch the free body diagram

b- what is the net force on the charge?

c- what direction is the magnetic force directed? explain

d- determine the magnitude and direction of the magnetic field needed so that the charge can pass through the plates undeflected including all work
