The Electric field at a point is
A. always continuous.
B. continuous if there is no charge at that point.
C. discontinuous only if there is negative charge at that point.
D. discontinuous if there is a charge at that point.
The correct answers are the options (b,d)
Explanation: Electric field lines cannot be defined at a point where a charge is present. While at any point electric field will be continuous if only one charge is present in the medium.
