Question

Which expression gives the magnitude of the electric field on a charged conductor surface?

पर्याय

• \[E=\sigma+\varepsilon_0\]

• \[E=\frac{\sigma}{\varepsilon_0}\]

• \[E=\sigma\varepsilon_0\]

• \[E=\frac{\varepsilon_0}{\sigma}\]

Answer 1

The magnitude form of the surface-field result is \(E=\frac{\sigma}{\varepsilon_0}\). The vector form additionally includes the outward normal unit vector.
