Conducting Spheres and Their Charge

[Nathew]

Homework Statement

Suppose we have three identical conducting spheres and one of them carries a charge of Q. if they are lined up in a row and then separated one at a time without grounding them...
a. only one will be charged with Q
b. they will all be discharged
c. one of them will have a charge of Q/2
d. they will each have a charge of Q/3
e. none of these

Homework Equations

The Attempt at a Solution

my guess was d, but i don't really understand and grasp the question/concept. The answer is C. If someone could guide me in the right direction that would be great.

Wait, I believe i got it. So when the 3 balls are together the charge Q spreads out as much as possible making the balls on either end Q/2 and the middle conductor with no charge. When one of the end balls is removed it keeps the charge of Q/2 and the process happens again with the other two balls. Is this right?

Yes.
