Transcribed Image Text:Before the advent of solid-state electronics, vacuum tubes
were widely used in radios and other devices. A simple
type of vacuum tube known as a diode consists essentially
of two electrodes within a highly evacuated enclosure
One electrode, the cathode, is maintained at a high
temperature and emits electrons from its surface. A
potential difference of a few hundred volts is maintained
between the cathode and the other electrode, known as
the anode, with the anode at the higher potential (gure

Part A
Suppose a diode consists of a cylindrical cathode with a radius of 6.200-10 cm. mounted coaxially within a cylindrical
anode with a radius of 0.5580 cm. The potential difference between the anode and cathode is 375 V An electron leaves
the surface of the cathode with zero inihal speed (0) Find its spood end when it strikes the anode
Express your answer numerically in meters per second.
