1.Three identical conducting spheres initially have the following charges: sphere A, 4Q; sphere B, −6Q; 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...

Select Tru or False. 1. A conducting sphere with charge Q at equilibrium has zero E field inside it. The E field outside is the same as that of a point charge Q, E=keQ/r2. The potential outside it is the same as that of a point charge Q. V= keQ/r. (r is the distance to the center). The potential inside the conducting sphere is equal to the potential at its surface. V= keQ/R. (R is the radius of the sphere)...

Packing material made of pieces of foamed polystyrene can easily become charged and stick to each other. Given that the density of this material is about 35kg/m3, estimate how much charge might be on a 2.0 cm -diameter foamed polystyrene sphere, assuming the electric force between two spheres stuck together is equal to the weight of one sphere.
