Magnitude of electric field due to a point charge +Q experienced by a test charge q at a distance r from the point charge +Q is equal to:

Magnitude of dielectric force experienced by the point charge/Q Magnitude of electric force experienced by the test charge/q Magnitude of repulsive force between the point charge and the test charge Magnitude of electric force experienced by point charge Q multiplied by the magnitude of charge on the test charge

Magnitude of electric force experienced by the test charge/q

The correct answer is Option (2) → Magnitude of electric force experienced by the test charge/q $E=\frac{F}{q}$ Hence option (2) is the correct.
