- Homework Statement
- Find the magnitude of the electric field of a large plate with surface charge density of 300Cm2 at a point 2.00 m away from the surface?
- Relevant Equations
- E = σ/2e0
I thought it might be the case that the "2m away" wasn't applicable as the electric field doesn't change if the point away is less than the length of the plate, so I thought I should use the equation listed. All examples I can find talk about two charged plates, or the effect on cylinders through or around a charged plate.
