Question
Explain the concept of electric field.
✓
Answer
- The space around a charge gets modified when a test charge is brought in that region, it experiences a coulomb force. The region around a charged object in which coulomb force is experienced by another charge is called electric field.
- Mathematically, electric field is defined as the force experienced per unit charge.
- The coulomb force acts across an empty space (vacuum) and does not need any intervening medium for its transmission.
- The electric field exists around a charge irrespective of the presence of other charges.
- Since the coulomb force is a vector, the electric field of a charge is also a vector and is directed along the direction of the coulomb force, experienced by a test charge.
