Chapter 22, Problem 22.57P

(a) An insulating sphere with radius a has a uniform charge density ρ. The sphere is not centered at the origin but at r = b . Show that the electric field inside the sphere is given by E  =  ρ ( r     b ) / 3 0 . (b) An insulating sphere of radius R has a spherical hole of radius a located within its volume and centered a distance b from the center of the sphere, where a < b < R (a cross section of the sphere is shown in Fig. P22.57). The solid part of the sphere has a uniform volume charge density ρ. Find the magnitude and direction of the electric field E inside the hole, and show that E is uniform over the entire hole. [Hint: Use the principle of superposition and the result of part (a).]

In free space, a linear charge density > is on the z axis. Get the electric force over a unit charge "q" located at P (1, 2, 3) m if the linear charge density is in -4 m < z < 4m = 2μC m Give the answer in unit vectors terms.
An insulating sphere of radius R = 0.12 m has a uniform surface charge density equal to5.5 mC>m2. A point charge q = 0.83 mC is a distance r = 0.44 m from the center of thesphere. Find the magnitude of the force exerted by the sphere on the point charge.
Charge of a uniform density (9 pC/m2) is distributed over the entire xy plane. A charge of uniform density (2 pC/m2) is distributed over the parallel plane defined by z = 2.0 m. Determine the magnitude of the electric field for any point with z = 3.0 m.
