Source: safalta.comNote that this ‘influence’ is simply the electrostatic force that a charge is able to exert over another. However, when describing fields, we require a quantity (scalar or vector) that is independent of the charge acting on and only dependent on the influence and the spatial distribution. So in simple terms, we can describe the electrostatic field keeping the force exerted by a point charge on a unit charge into consideration. In other terms, we can describe the electric field as the force per unit charge.

Therefore, the force applied per unit charge is
It is to be noted that the electric field is a vector quantity, which is described at every point in space, the value of which is reliant only upon the radial distance from q.
The trial charge q0 itself has the capability to exert an electric field around it. Therefore, to prevent the dominance of the test charge, we must preferably make it as tiny as we can.
