Charge Q is uniformly distributed on a square plate of size L*L.
Find the electric field (magnitude and direction) at the point P
which is at a distance L above the center of the square.
(Please define you own coordinate system)

L
先求v，但在積平面時
ρ +L/2 +L/2 dXdY
v= ________ ∫ ∫ ________________________
4πεο -L/2 -L/2 __________________
√ 2 2 2
X + Y + Z
就卡住了.....
請問這要怎積呢??
還是能有更好的解法??
謝謝
