Question
what is scenario 2?
sapin9.iesam You have four identical conducting spheres: A, B. C, and D. In each scenario below, sphere A starts with a charge of +Q, while B, C, and D start out with no net charge, and then the spheres are louched to each other and separated in the order desonbed Any spheres not in contact are held very far away. For each scenario, give the final charge of sphere B as a whole number fraction of Q. For example, if you decide that the final charge of Sphere B is Q7, enter .1" in the numerator and in the denominator again.r Betore Remember! Belore each scenario begins, spheres A, B, C, and D are reset to charges of +Q, 0, 0, and 0 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 Scenario 2 A and B touch and are separated, then B and C touch and are separated, then C and D touch and are 8-6 x Q 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. 16
Explanation / Answer
Scenario 1:
A and B touch and are separated A and B both Q/2
A and C touch and are separated A and C both Q/4
A and D touch and are separated A and D both Q/8
Scenario 3:
A and D touch and are separated A and D both Q/2
D and C touch and are separated D and C both Q/4
D and A touch and are separated D and A both ½(Q/2 + Q/4) = 3Q/8
A and B touch and are separated A and B both 3Q/16
