Review Part A 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 Suppose a diode consists of a cylindrical cathode with a radius of 6.200x102 cm , mounted coaxially within a cylindrical anode with a radius of 0.5580 cm . The potential essentially of two electrodes within a highly evacuated difference between the anode and cathode is 320 V . An electron leaves the surface of the cathode with zero initial speed (Vinitial = 0). Find its speed vfinal when it strikes the enclosure. One electrode, the cathode, is maintained at a anode. high temperature and emits electrons from its surface. A potential difference of a few hundred volts is maintained Express your answer numerically in meters per second. between the cathode and the other electrode, known as > View Available Hint(s) the anode, with the anode at the higher potential.
