The gure shows four identical conducting spheres that are actually well separated from one another. Sphere W(with an initial charge of zero) is touched to sphere A and then they are separated. Next, sphere W is touched to sphere B (with an initial charge of '326) and then they are separated. Finally, sphere W is touched to sphere C (with an initial charge of 426'), and then they are separated. The nal charge on sphere Wis 146. What multiple of 6: gives the initial charge on sphere A? .40 8 (:0 W0
