Could someone PLEASE help me with these quick physics questions?

(1) (4 pts.) Suppose a region of space has a uniform electric field, directed towards the right, as shown in the figure. Which statement about the electric potential is true? Explain why. (a) The potential at all three locations (A, B, C) is the same because the field is uniform. (b) The potential at points A and B are equal, and the potential at point C is higher than the potential at point A. (c) The potential at points A and B are equal, and the potential at point C is lower than the potential at point A. (d) The potential at point A is the highest, the potential at point B is the second highest, and the potential at point C' is the lowest. E A . C B(2) (1 pt.) The charge on the square plates of a parallel-plate capacitor is Q. The potential across the plates is maintained with constant voltage by a battery as they are pulled apart to twice their original separation, which is small compared to the dimensions of the plates. What is the amount of charge on the plates now equal to?(3) (1 pt.) The graph in the figure shows the variation of the electric potential V (measured in volts) as a function of the radial direction r (measured in meters). On a separate graph show the electric field corresponding to the potential over the same range of r. V ( V ) 4- 3+ - N 1 2 3 4 5 6 8 r (m ) LAWNL
