(N/A) The principle of superposition states that the total force on a given charge due to a number of other charges is the vector sum of the individual forces exerted on the given charge by each of the other charges.
Mathematically,if a charge $q_0$ is in the presence of charges $q_1, q_2, ..., q_n$,the total force $\vec{F}$ on $q_0$ is given by:
$\vec{F} = \vec{F}_1 + \vec{F}_2 + ... + \vec{F}_n$
where $\vec{F}_i$ is the force exerted on $q_0$ by the $i$-th charge $q_i$ as calculated by Coulomb's law,independent of the presence of other charges.
