The potential between the two parallel plates used as speed separator is 5,0V and the magnetic field in the inner-plate region is 2,0T. What will be the speed of the protons that will pass through this speed separator without deviation.(mp=10-27 Kg) (NOTE: you will determine the polarization direction of the plates and the direction of the magnetic field.)

Consider two infinite plates, both parallel to the xy plane of a coordinate system. The top plate is at the height z = +5cm and carries a uniform charge distribution of ?= +3nC/m2. The bottom plate is at height z = - 5cm and carries a uniform charge distribution of ?= -3nC/m2. The space between the plates is filled with air. Between the plates runs a long wire along the y-axis (at z=0 and x=0), carrying a current of 10A....
