A very long uniform line of charge with charge per unit length λ = +5.00 μC/m lies along the xx-axis, with its midpoint at the origin. A very large uniform sheet of charge is parallel to the xy-plane; the center of the sheet is at z = +0.600 m. The sheet has charge per unit area σ = +8.00 μC/m2, and the center of the sheet is at x=0, y=0. Point A is on the z-axis at z = +0.300 m, and point B is on the z-axis at z = -0.200 m.What is the potential difference VAB=VA−VB between points A and B?
Two uncharged, conducting spheres are separated by a distance d. When charge −Q is moved from sphere A to sphere B, the Coulomb force between them has magnitude F0. Is the Coulomb force attractive or repulsive? If an additional charge −Q is moved from A to B, and the distance between the centres of the spheres is doubled, what is the ratio of the new Coulomb force to the original Coulomb force?
A point charge, q = -5.00 nC, and m = 2.00 x 10-14 kg, is shot vertically upward with an initial speed of 2.00 x 103 m/s from a thin, infinite, planar sheet of uniform charge with surface charge density of σ = +4.00 (nC)/m^2. To what vertical elevation will q rise above the sheet of charge? Neglect gravity.

(a) r = 1.00 cm magnitude direction (b) r = 3.00 cm magnitude N/C direction (c) r = 4.50 cm magnitude N/C direction (d) r = 7.00 cm magnitude N/C directionarrow_forwardA nonuniform, but spherically symmetric, insulating sphere of charge has a charge density ρ(r)ρ(r) given as follows: ρ(r)=ρ0(1−4r/3R) for r≤R ρ(r)=0 for r≥R where ρ0 is a positive constant. This means that the amount of charge per unit volume varies with distance from the center of the sphere. Hint: The charge enclosed in a given spherical shell of inner radius R1 and outer radius R2 is Qenc=∫R2R1 ρ(r)dV where dV=4πr^2dr (in other words, you have to integrate over each spherical shell of radius rr from the inner radius to the outer radius). Notice that if the charge is uniform, so that ρρ is a constant, and you have a solid sphere with inner radius zero and outer radius R (i.e. a normal sphere) you can pull ρρ out of the integral and it reduces to the simple expression Qenc=ρ4/3πR^3. For a non-uniformly charged sphere, however, as in this problem, you have to use the full integral to find the charge enclosed in a given region.
