Question

The figure shows three identical conducting bubbles A, B, and C floating in a conducting container that is grounded by a wire. The bubbles initially have the same charge. Bubble A bumps into the container’s ceiling and then into bubble B. Then bubble B bumps into bubble C, which then drifts to the container’s floor.When bubble C reaches the floor, a charge of -3e is transferred upward through the wire, from the ground to the container, as indicated. (a) What was the initial charge of each bubble? When (b) bubble A and (c) bubble B reach the floor, what is the charge transfer through the wire? (d) During this whole process, what is the total charge transfer through the wire?

Explanation / Answer

so the answer to

(a)+4e corroborates that (12e- rise through the grounding wire to neutralize & thereby ground the +12e total).

The answer to

(b) is -2e upward

(c) -3e upward.

The answer to (d) is -12 e upward

The initial collision of Bubble A with the container's ceiling could result in a -4e discharge upward from the grounding wire to ground the charge of A, and I tried to use the # of collisions of A to account for a charge decrease from +4e to +2e for Bubble A, resulting in the -2e upward
