The Electric field at a point is

Options

A. always continuous.
B. continuous if there is no charge at that point.
C. discontinuous only if there is a negative charge at that point.
D. discontinuous if there is a charge at that point.

Answer

B, D

Explanation

Electric field lines originate or terminate at the location of charge. Hence, the ends of electric field line lies on the charge or it is extended up to infinity. Electric field lines are continuous in a region where there is no charge. Electric lines are discontinuous at the location of charge.
