Two point charges are on the x axis. Charge 1 is +q and is located at x= -1.0 m; charge 2 is +2q and is located at x=1.0 m. Make a sketches of the equipotential surfaces for this system (a) out to a distance about 2.0 m from the origin and (b) far from the origin. In each case, indicate the direction in which the potential increase.
From the sound of the question, it seems to be a conceptual check, in the first part, the equipotential surface will resemble a figure 8, however the farther we get form the origin, the more the equipotential surface resembles a circle enclosing both charges. This is much like the arguments of symmetry made for calculations such as the electric field of an infinite plate of charge. and of course the potential energy will increase the farther you get from the charges if you mean the point to point potential energy in a constant field. However given the context of the question is it asking about the two point charges in question? please re post about that cause now I'm curious.
