A:
Electric Field: Electric field at a point is defined as the electric force acting on a unit positive charge assumed to be present at that point.
The magnitude of the electric field due to a point charge at distance from it is given by the formula.
where is Coulomb's constant.
The direction of the electric field:
The direction of the electric field due to a point charge is away from it if it is positive. And the direction of the electric field due to a point charge is towards it if it is negative.
