Is electric field a scalar or a vector quantity? Why?
(N/A) The electric field is a $vector$ quantity.
It is defined as the force experienced by a unit positive test charge placed at a point in the field.
Mathematically, $\vec{E} = \frac{\vec{F}}{q_0}$.
Since force $(\vec{F})$ is a vector quantity and the electric field has both a specific magnitude and a definite direction (the direction of the force on a positive test charge), it satisfies the requirements of a vector quantity.
