An electric field is a force field surrounding an electrically charged object. It exerts a force on other charged objects in its vicinity.
The magnitude of an electric field is calculated by dividing the force exerted on a test charge by the magnitude of the test charge itself.
The electric field magnitude midway between two charges is significant because it represents the strength of the electric force at that point. It is also used to calculate the potential energy of a test charge at that point.
The electric field magnitude at the midway point between two charges is calculated by adding the individual electric fields of each charge using vector addition.
The electric field magnitude at the midway point between two charges is inversely proportional to the distance between the two charges. As the distance increases, the electric field magnitude decreases and vice versa.
