In figure two positive charges, $q_2$​ and $q_{3​}$ fixed along the $y-$axis, exert a net electric force in the $+x$ direction on a charge $q_1$​ fixed along the $x-$axis. If a positive charge $Q$ is added at $(x, 0),$ the force on $q_1​:$
Consider three converging lenses $ L_1, L_2$ and $L_3 $ having identical geometrical construction. The index of refraction of $ L_1$ and $L_2$ are $\mu_1$ and $\mu_2$ respectively. The upper half of the lens $L_3$ has a refractive index $\mu_1$ and the lower half has $\mu_2$. A point object $O$ is imaged at $O_1$ by the lens $L_1$ and at $O_2$ by the lens $L_2 $ placed in same position. If $L_3$ is placed at the same place:
