let a parallel plate capacitor be in the vacuum with one plate cathode located at x=0 emitting electrons which are collected at the other plate anode located at x=d the arrangement makes up a vacuum diode lets the volume charge density within the capacitor be given by pv(x)=-(4/9) E0V0d^-4/3 x^-2/3 C/m^3 where the cathode is located at x=0 and the anode at x=d . The voltage between the anode and the cathode is V0 and the total charge in 1m^2 cross section is -12 nC .1 find the Vo if d = 6mm . 2 find d if vo=5v .
