Which of the following statements is correct? The electric field at a point is
Correct answer: D. Discontinuous only if there is a charge at that point.
- A. Continuous if there is a charge at that point.
- B. Always continuous.
- C. Discontinuous only if there is a negative charge at that point.
- D. Discontinuous only if there is a charge at that point.
Explanation
The electric field caused by any charge will be continuous if there is no other charge in the medium. It will be discontinuous if there is a charge at that viable point. Charged particles tend to change the emergence and divergence of continuous electric field lines.

About Electrostatics
Electrostatics describes forces between charges through Coulomb's law, electric fields and field intensity, then uses electric potential to measure energy per unit charge. Capacitors store charge and electrical energy, with capacitance depending on geometry and dielectric material, not simply on the amount of charge present.
