What is the charge per unit area in $C / m^{2}$ , of an infinite plane sheet of charge if the electric field produced by the sheet of charge has magnitude 3.0 N/C?

Open in App

Solution

The electric field due to infinite charge sheet is $E = \frac{σ}{2 ϵ_{0}}$
So, the charge per unit area, $σ = 2 ϵ_{0} E = 2 \times (8.85 \times 10^{- 12}) \times 3 = 5.31 \times 10^{- 11} C / m^{2}$
