Before the advent of solid-state electronics, vacuum tubes were widely used in radios and other devices....
Suppose a diode consists of a cylindrical cathode with a radius of 6.200×10−2 cmcm , mounted coaxially within a cylindrical anode with a radius of 0.5580 cmcm . The potential difference between the anode and cathode is 205 VV . An electron leaves the surface of the cathode with zero initial speed (vinitial=0vinitial=0). Find its speed vfinalvfinalv_final when it strikes the anode.
