Question

For a large sheet of charge, what is the electric field due to each plate in terms of surface charge density \[\sigma\]?

Options

• \[\frac{2\sigma}{\varepsilon_0}\]

• \[\frac{\sigma}{\varepsilon_0}\]

• \[\frac{\sigma}{2\varepsilon_0}\]

• \[\frac{\varepsilon_0}{2\sigma}\]

Answer 1

The electric field due to each large sheet of charge is \[\frac{\sigma}{2\varepsilon_0}\]. Between two oppositely charged plates, the two field contributions add.
