[題目] Two infinite parrallel plates separated by distance s are at
potential 0 and V0.Use Poission's equation to find the potential
V at x=5 in the region between the plates where the space charge
density is p=p0(x/s).The distance x is measured from the plate
at zero potential
(Use V0=10 s=10 p0=8.841921*10^-12 4πεo=9*10^-9)
[瓶頸] 我覺得x=5位置的V不就剛好在V=0和V=V0=10的中間 所以此位置的V就等於
(0+10)/2=5 但感覺應該沒這麼簡單 請大家幫幫我謝謝
(寫寫自己的想法,方便大家為你解答)
