Question

The electric field at a point is

• A. Always continuous
• B. Continuous if there is no charge at that point
• C. Discontinuous if there is a charge at that point
• D. Both (B) and (C) are correct

Answer 1

The correct option is D

Both (B) and (C) are correct

The explanation for correct answer:

Option (D): Both (B) and (C) are correct

1. The region of space in which an electric charge experiences a force is known as the Electric field.
2. The direction of the electric field is along the direction in which the positive test charge placed in the field would tend to move if free to do so.
3. The electric field at a point will be continuous only if it is unaffected by other charges at that point.
4. If a charged particle is placed in its pathway, the electric field lines would start to converge or diverge by losing their continuity.
5. The electric field because of any charge will be discontinuous if there is any other charge present in that medium.

Therefore, the electric field at a point is discontinuous if there is a charge at that point and it is continuous if there is no charge at that point.
