| (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. |
Choose the correct option:
| 1. | (a), (b) | 2. | (b), (d) |
| 3. | (c), (d) | 4. | (a), (d) |
(2) Hint: The electric field lines originate from a positive charge and end at a negative charge.
The electric field due to a charge Q at a point in space may be defined as the force that a unit positive charge would experience if placed at that point. Thus, the electric field due to the charge Q will be continuous, if there is no charge at that point. It will be discontinuous if there is a charge at that point.
