vo y E A uniform field E = -150000jN/C exists between two plates of length L = 3 cm, as shown in the figure above. A proton is fired at an angle of 40° to the a axis with an initial speed of 7300000 m/s. a) Find its vertical coordinates as it emerges from the plate, assuming the proton will not hit any plate in the process. çm b) Find the angle at which it emerges. degrees to the x axis.
