Homework Statement
3 Infinitely large non conductiong sheets are uniformly charged with surface charge densities Sigma1 = +2x10^-6c/m^2, Sigma2 = +4x10^-6c/m^2, Sigma3 = -5.0x10^-6c/m^2. Distance L = 1.6cm. What is the magnitude and direction of the net electric field at point P?
* P
| L/2
________________ Sigma3
|
|
| 2 *L
|
________________ Sigma2
| L
|
________________ Sigma 1
Homework Equations
The only 1 i know of is E = Sigma/(2*εnot)
The Attempt at a Solution
Es1 + Es2 + Es3 = Etot at P.
So my teacher never really taught us about non-conducting sheets over any distance, and instead told us to google it and ask on forums instead. Please me through how you do this, i can't find a formula that deals with distance between non-conducting sheets.
