Electric Field
Is defined as the electric force per unit charge. The direction of the field Is taken to be the direction of the force it would exert on a positive test charge.
Electric Field
is radially outward from a positive charge and radially in toward a negative point charge.
Magnitude of an Electric Field (through force and charge).
The magnitude of the electric field is directly proportional to the electrical force acting on it and inversely proportional to the charge given.
Magnitude of an Electric Field (through charge and radius).
The magnitude of the electric field is directly proportional to the product of constant and electrical charge acting on it and inversely proportional to the square of radius.
