Explain the concept of electric field.

1.	Explain the concept of electric field.
Answer» 1. 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. 2. Mathematically, electric field is defined as the force experienced per unit charge. 3. The coulomb force acts across an empty space (vacuum) and does not need any intervening medium for its transmission. 4. The electric field exists around a charge irrespective of the presence of other charges. 5. 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.

1. 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.

2. Mathematically, electric field is defined as the force experienced per unit charge.

3. The coulomb force acts across an empty space (vacuum) and does not need any intervening medium for its transmission.

4. The electric field exists around a charge irrespective of the presence of other charges.

5. 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.
