Question

Which expression gives the electric field on a charged conductor surface in vector form?

विकल्प

• \[\vec{E}=\sigma\varepsilon_0\hat{n}\]

• \[\vec{E}=\frac{\sigma}{\varepsilon_0}\]

• \[\vec{E}=\frac{\sigma}{\varepsilon_0}\hat{n}\]

• \[\vec{E}=\frac{\varepsilon_0}{\sigma}\hat{n}\]

Answer 1

The vector expression is \(\vec{E}=\frac{\sigma}{\varepsilon_0}\hat{n}\). The outward normal unit vector \(\hat{n}\) specifies the field's direction.
