Question
Chapter 2, Problem 2.9P
(a)
To determine
What is the velocity of an electron midway between the electrodes and at the instant of striking the plate, if the electrons are emitted from the cathode with zero velocity if a diode vacuum tube consists of a cathode and an anode spaced 5-mm apart, if 300 V are applied across the plates?
(b)
To determine
What is the average force exerted on the anode if the plate current is 20 mA?
