Assuming S to be the area of the electrodes in the space-charge-limited vacuum diode in Fig. 5-2, find
a) V ( y )and E ( y ) within the interelectrode region,
b) the total amount of charge in the interelectrode region,
c) the total surface charge on the cathode and on the anode,
d) the transit time of an electron from the cathode to the anode with V 0 = 200 (V) and d = 1 (cm).
