An electron is fired at a speed v = 3.1 x 10° m/s and at an angle 0, = 36.8° between two parallel
conducting plates as shown in the figure. If s 1.8 mm and the voltage difference between the plates is
AV = 98.8 V, determine how close, w, the electron will get to the bottom plate. Put your answer in
meters and include at 6 decimal places in your answer. Do not include units. The x-axis of the
coordinate system is in the middle of the parallel plate capacitor.
