The electric field intensities at points between and outside two thin, separated, parallel sheets of infinite extent carrying like charges of the same surface charge density σ are and respectively.

Question

Accepted Answer

(2) 0, σ/(ε₀). Idea: an infinite sheet with charge density σ gives a uniform field σ/(2ε₀) on each side, pointing away from the sheet (for positive σ). Add the two sheets' fields. Between the sheets: sheet 1's field points towards sheet 2 and sheet 2's points towards sheet 1, so E=σ/(2ε₀)-σ/(2ε₀)=0. Outside, on either side: both fields point away from the pair, in the same direction, so E=σ/(2ε₀)+σ/(2ε₀)=σ/(ε₀). So the field is 0 between the sheets and σ/(ε₀) outside them.
