[領域] 電磁學 (題目相關領域) [來源] Griffiths (課本習題、考古題、參考書...) [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) -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.116.117.10
Glamdring:應該要考慮charge density的貢獻吧 11/09 22:14
Glamdring:還是乖乖寫poisson eq算一算吧 11/09 22:15
