An electron traveling horizontally with a speed v0 = 1.5×107 m/s enters a uniform, vertical electric field created by two oppositely charged parallel plates as shown inFigure. The electric field between the plates has a magnitude of E = 2.0 ×104 N/C. The separation between the plates is s = 1.0 cm, and the vertical deflection of theelectron as it passes between the plates is d = 0.60 cm.
(a) What is the potential difference between the plates?
(b) Which plate is at the higher voltage?
(c) Through what potential difference does the electron travel as it passes between the plates?
(d) What is the speed of the electron as it leaves the area between the plates?
