A point charge q1 = +6.0e is fixed at the origin of a rectangular coordinate system, and a point charge q2 = - 10e is fixed at x = 8.6 mm, y = 0. The locus of all points in the xy plane for which V = 0 (other than infinity) is a circle centered on the x axis, as shown in Fig.
Find (a) the location x, of the center of the circle and
(b) the radius R of the circle.
(c) Is the xy cross section of the 5 V equipotential surface also a circle?
