Q: A solid copper sphere has a net positive charge. The charge
A solid copper sphere has a net positive charge. The charge is distributed uniformly over the surface of the sphere, and the electric field inside the sphere is zero. Then a negative point charge outs...
See AnswerQ: Charge Q is distributed uniformly throughout the volume of an insulating sphere
Charge Q is distributed uniformly throughout the volume of an insulating sphere of radius R = 4.00 cm. At a distance of r = 8.00 cm from the center of the sphere, the electric field due to the charge...
See AnswerQ: A conductor with an inner cavity, like that shown in Fig
A conductor with an inner cavity, like that shown in Fig. 22.23c, carries a total charge of +5.00 nC. The charge within the cavity, insulated from the conductor, is -6.00 nC. How much charge is on F...
See AnswerQ: A very large, horizontal, nonconducting sheet of charge has uniform
A very large, horizontal, nonconducting sheet of charge has uniform charge per unit area s = 5.00 × 10-6 C/m2. (a). A small sphere of mass m = 8.00 × 10-6 kg and charge q is placed 3.00 cm above the s...

An infinitely long cylindrical conductor has radius R and uniform surface charge density
See AnswerQ: Two very large, nonconducting plastic sheets, each 10.0
Two very large, nonconducting plastic sheets, each 10.0 cm thick, carry uniform charge densities s1, s2, s3, and s4 on their surfaces (Fig. E22.30). These surface charge densities have the values s1 =...
See AnswerQ: A rubber balloon has a single point charge in its interior.
A rubber balloon has a single point charge in its interior. Does the electric flux through the balloon depend on whether or not it is fully inflated? Explain your reasoning.
See AnswerQ: Suppose that in Fig. 22.15 both charges were positive
Suppose that in Fig. 22.15 both charges were positive. What would be the fluxes through each of the four surfaces in the example? Fig. 22.15:
