Two point charges, 9, = -1.1 pc and q2 = 1.1 pc, are placed on the x axis at x, = 2.6 m and x2 = -2.6 m, respectively (see figure below). 42 91 R (x2,0) 0 (x1, 0) (a) What are the electric potentials at the points P (0, 2.6 m) and R (5.2 m, 0)? V. s II (b) Find the work done in moving a 1.0-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 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. O Yes, because the work done depends only on the length of the path chosen. O No, because the work done doesn't depend on the change in potential.
