why does electrostatic potential obey superposition?
it's a solution of poisson's equation and solutions of poisson's equation definitely do not obey superposition!

If [tex] \nabla^2 \varphi_1 = \rho_1 / \epsilon_0 [/tex] and [tex] \nabla^2 \varphi_2 = \rho_2 / \epsilon_0 [/tex], then [tex] \varphi_1 + \varphi_2 [/tex] satisfies [tex] \nabla^2 \varphi = (\rho_1 + \rho_2) / \epsilon_0 [/tex], i.e. the potential of the combined charge distribution [tex] \rho_1 + \rho_2 [/tex] is the sum of the potentials of the individual distributions.
