Detailed Solution

Electric field lines of force can never intersect each other because if they do so then at the point of intersection two tangents can be drawn which would mean two directions of force at that point which is impossible.
If there are n point charges q₁ , q_{2. . . .} q_n, then each of them will produce the same intensity at any point which it would have produced in the absence of other point charges. Hence, intensity of $\vec{E}$ is resultant of

${\vec{E}}_{1}, {\vec{E}}_{2} \dots . {\vec{E}}_{n} as \vec{E} = {\vec{E}}_{1} + {\vec{E}}_{2} + \dots + {\vec{E}}_{n}$
