A vacuum tube diode (see Exercise 23.27) consists of concentric cylindrical electrodes, the negative cathode and the
Question:
V(x) = Cx4/3
Where x is the distance from the cathode and C is a constant, characteristic of a particular diode and operating conditions. Assume that the distance between the cathode and anode is 13.0 mm and the potential difference between electrodes is 240 V.
(a) Determine the value of C.
(b) Obtain a formula for the electric field between the electrodes as a function of x.
(c) Determine the force on an electron when the electron is halfway between the electrodes.
