Which of the following is a correct representation of field lines and equipotent

Question

Which of the following is a correct representation of field lines and equipotential lines for a parallel plate capacitor (Field lines are thin with arrows on them. Equipotentials are thicker) Consider the equation V = k_e Q/r. Which of the following statements is false: This equation represents a scalar This expression is valid for a point source charge This expression is valid for a constant electric field The electric potential energy can be calculated by multiplying V with the value of the test charge It is given that the electric field at a point in space is given by E and the potential at that point is given by V. What is the force acting on a test charge, q? qV qE kqQ/r^2 More information is needed to answer this question Remember the experiment you did in class where you plotted out the equipotential lines due to a dipole? Now suppose instead of two points, the black sheet of conductive paper had one point and one line as shown below. If you had repeated your experiment with this new sheet of black paper, what result would you have obtained for equipotential lines?
