The direction of the force experienced by a positive test charge placed at that point.

(A) The electric field intensity $\vec{E}$ at a point is defined as the force $\vec{F}$ experienced by a unit positive test charge $q_0$ placed at that point.Mathematically,$\vec{E} = \frac{\vec{F}}{q_0}$.Since $q_0$ is a positive scalar,the direction of the electric field intensity $\vec{E}$ is the same as the direction of the force $\vec{F}$ experienced by the positive test charge.
