48 In Fig. 21-41, three identical con- ducting spheres form an equilateral tri- angle of side length d= 20.0 cm. The sphere radii are much smaller than d, and the sphere charges are q4 = -2.00 nC, q = -4.00 nC, and qc = +8.00 nC. (a) What is the magnitude of the electro- static force between spheres A and C? The following steps are then taken: A and B are connected by a thin wire and then disconnected; B is grounded by the wire, and the wire is then removed; B and C are connected by the wire and then discon- nected. What now are the magnitudes of the electrostatic force (b) between spheres A and Cand (c) between spheres B and C? C. Figure 21-41 Problem 48.
