The minimum field required to break down air and turn it into a conductor is 3.0 106 N/C.arrow_forwardThree identical conducting spheres are fixed along a single line. The middle sphere is equidistant from the other two so that the center-to-center distance between the middle sphere and either of the other two is 0.125 m. Initially, only the middle sphere is charged, with qmiddle = +35.6 nC. The middle sphere is later connected by a conducting wire to the sphere on the left. The wire is removed and then used to connect the middle sphere to the sphere on the right. The wire is again removed. a. C What is the charge on each sphere? b.

- Two identical conducting spheres labeled A and B have net charges q1 = 4 q. (>0) and q2 = -6 9o, respectively. A third conducting sphere identical to the others is initially uncharged. This third sphere is touched first to the first sphere and then to the second sphere before being removed from the area. The net charge on the second sphere will now be x 9o.arrow_forwardIn the figure three identical conducting spheres initially have the following charges: sphere A, 4Q; sphere B, -9Q; and sphere C, 0. Spheres A and B are fixed in place, with a center-to-center separation that is much larger than the spheres. Two experiments are conducted. In experiment 1, sphere C is touched to sphere A and then (separately) to sphere B, and then it is removed. In experiment 2, starting with the same initial states, the procedure is reversed: Sphere C is touched to sphere B and then (separately) to sphere A, and then it is removed. What is the ratio of the electrostatic force between A and B at the end of experiment 2 to that at the end of experiment 1?arrow_forwardTwo conducting spheres are far apart. The smaller sphere of radius R carries a total charge Q. The larger sphere is neutral and has a radius r where r =4.5 R.
