Consider a beam of protons traveling though a vacuum, where each proton has a velocity of need to design a means to change the direction of the proton beam by 90°. Consider the charged parallel plates separated by a distance d = 60 cm as depicted in Figure P17.93. Small holes have been drilled into the bottom plate at right angles to one another to allow the beams to follow the trajectory shown. Calculate the electric field between the plates.
