The figure 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 Wis touched to sphere B (with an initial charge of -26e) and then they are separated. Finally, sphere Wis touched to sphere C (with an initial charge of 48e), and then they are separated. The final charge on sphere Wis 22e. What multiple of e gives the initial charge on sphere A? Jse correct number of significant ligits. The tolerance is + 1 in the W rd significant digit. Number i Units
