For each scenario below, there are four identical balls, A, B, C, and D, which conduct, and ball A starts with a charge of +Q, while B, C, and D have zero net charge. The balls are then touched to each other and separated as described below. Assume that any balls not in contact are placed very far away. For each scenario, find the final charge of ball D as a whole number fraction of Q. For example, if the final charge of ball D is Q/5, enter "1" in the numerator and "5" in the denominator. Remember, before each scenario begins, balls A, B, C, and D have set up to have charges of +Q, 0, 0, and 0, respectively. Scenario 1: A and B touch and are separated, then A and C touch and are separated, then A and D touch and are separated. Qp = xQ Scenario 2: A and B touch and are separated, then B and C touch and are separated, then C and D touch and are separated. Qp = Scenario 3: A and D touch and are separated, then D and C touch and are separated, then D and A touch and are separated, then A and B touch and are separated.
