Charged Insulators connected with a switch Conflicting Contention Task Important concepts: Two charged INSULATORS are connected with a wire, with an open switch in the middle they are charged as shown, and have the same radius. Three students are discussing what happens if the switch is closed. Arturo) Since the spheres are the same size, charge will move until there is an equal charge of 40 nC on each. Beth) I agree, but since they are insulators, the charge will move very slowly. Eventually there will be the same charge of 40 nC on each, but it will take a long time, perhaps 5-10 minutes. Caitlin) No, since they are insulators the charge cannot move. It doesn't matter whether the switch is open or closed. Which of these students is correct? Aurturo Beth Caitlin none Two charged metal spheres are connected by a wire. Sphere A is larger than sphere B, as shown. The magnitude of the electric potential of sphere A: is greater than that at the surface of sphere B. is less than that at the surface of sphere B. is the same as that at the surface of sphere B.Explanation / Answer
The particles of the insulator do not permit the free flow of electrons.
So
Option (C) is Correct.
As the two Sphere are connected by the wire, the charge will be same on both the speher,
Potential due to Charged sphere is given by, V = K*q/r
At surface, rb < ra
So, Vb > Va
Option B is correct.
