Two point charges, q, = -4.9 µC and q, = 4.9 µC, are placed on the x axis at x, = 3.4 m and x, = -3.4 m, respectively (see figure below). (x, 0) (x, 0) (a) What are the electric potentials at the points P (0, 3.4 m) and R (6.8 m, 0)? Vp = VR = V V (b) Find the work done in moving a 1.0-µC charge from P to R along a straight line joining the two points. (c) Is there any path along which the work done in moving the charge from P to R is less than the value from part (b)? Explain. O No, because the work done doesn't depend on the change in potential. O Yes, because the work done depends only on the length of the path chosen. O Yes, because the change in potential will vary depending on the path chosen. O No, because the work done depends only on the change in potential.
