An electron beam in a cathode-ray tube passes between two parallel plates that have a voltage difference of 300 V across them and are separated by a distance of 2 cm, as shown in the diagram.
a. In what direction will the electron beam deflect as it passes between these plates? Explain.
b. Using the expression for a uniform field, ΔV = Ed, find the value of the electric field in the region between the plates.
c. What is the magnitude of the force exerted on individual electrons by this field? (F = qE, q  1.6 x 10^-16 C)
d. What are the magnitude and direction of the acceleration of an electron? (m = 9.1 x 10^-31 kg)
e. What type of path will the electron follow as it passes through the region between the plates? Explain.
