Question
If two identical conducting spheres are in contact, any excess charge will be evenly distributed between the two. Three identical metal spheres are labeled A, B, and C. Initially, A has charge q, B has charge -qj2, and C is uncharged. What is the final charge on each sphere if C is touched to B, removed, and then touched to A? Express your answers in terms of q. Enter your answers separated by commas. Q_A, Q_B, Q_C = Starting again from the initial conditions, what is the charge on each sphere if C is touched to A, removed, and then touched to B? Express your answers in terms of q. Enter your answers separated by commas. Q_A, Q_B, Q_C =
Explanation / Answer
Part A)
Applying the Condition of equal distribuation of excess charge, we get:
QC=0.375q
QA= 0.375q
QB = -0.25q
Part B)
QB= 0
QC = 0
QA = 0.5q
