Electric field is the electrostatic force per unit charge acting on a vanishingly small test charge placed at that point. It is a vector quantity and the electric field inside a charged conductor is zero. Electric flux `phi` is the total number of electric lines of force passing through a surface in a direction normal to the surface when the surface is placed inside the electric field.
`phi=ointvecE.vec(ds)=q/epsilon_0`
The electric field at a point is

A

always continuous.

B

continuous if there is no charge at the point.

C

discontinuous only if there is a negative charge at that point

D

discontinuous if there is a charge at that point.
