Question
Problem 13(6.25 points) In the illustration, two particles carry the same amount of positive charge. Which of the dashed lines could be an equipotential line of the two charged particles? A) The vertical line that is located halfway between the charges B) The circle around one charged particle, with every point on the circle equidistant from the center of the charged particle. The horizontal line that runs directly through the center of each D)None of the three lines could be an equipotential line for both charges.Explanation / Answer
If we look at the electric field lines of two positive charges, we will understand why none of the dashed lines could be an equipotential. Option B can be ruled out as it is only for one charge. Option C can be ruled out as if we draw a straight equipotential line, it will not be perpendicular to electric field lines which is the foremost rule of field mapping. and there is no electric field in the middle of two like charges which rules out option A.
so we are left with only part D which is the correct answer
