- Three identical conducting spheres denoted as X, Y, and Z are separated in space. They have initial net charges of −2Q, −3Q, and 5Q, respectively. Sphere Z is touched to X and separated, then touched to Y and separated. Upon reaching electrostatic equilibrium, what is the final net charge of Y?Four conducting spheres labeled A, B, C and D are charged to the following values: qA = 2.0 ?C, qB = 3.0 ?C, qC = -2.0 ?C, qD = -6.0 ?C. The following three interactions then occur: qA is brought in contact with qC, then qC is brought in contact with qB and lastly qB is brought in contact with qD. [Report all answers in Coulombs.]What is the final charge of qB? What is the final charge of qC? What is the final charge of qD? What is the total final charge of the system?After building up some excess charge by scuffing your feet on a carpet, you transfer that charge to a neutral metal doorknob. Just after you do so, where is the charge? Spread out on the surface of the doorknob. Evaporated into the air. In the exact spot you touched and nowhere else. At the exact centre in the interior of the doorknob.
