Only perpendicular field lines contribute to flux. Why?
The flux due to an electric field is given by $E\cdot A$, which means only the electric field lines that are perpendicular to the area A count (same for the perpendicular component of the field, if it …

Why some forces follow superposition principle?
Let there be a system of $n$ source charges and a test charge $Q$. When we say superposition applies to electrostatic force, we conclude that the interaction between a given source charge and the test …
