Z.yFigure 2.11 Problem 2.7 Find the electric field a distance z from the center of a spherical surface of radiusR (Fig. 2.11), which carries a uniform charge density o. Treat the case z < R (inside) as wellas z > R (outside). Express your answers in terms of the total charge q on the sphere. [Hint:Use the law of cosines to write r in terms of R and 0. Be sure to take the positive square root:VR? + z? - 2Rz = (R – z) if R > z, but it's (z – R) if R < z.]

Problem 4.15 A thick spherical shell (inner radius a, outer radius b) is made of dielectric material with a "frozen-in" polarization P(r) = i where k is a constant and r is the distance from the center (Fig. 4.18).

Consider an infinitesimal segment located at an angular position θ on the semicircle, measured from the lower right corner of the semicircle at x=a, y=0. (Thus θ=π2 at x=0, y=a and θ=π at x=−a, y=0.) What are the x- and y- components of the electric field at point P (dEx and dEy) produced by just this segment? Express your answers separated by a comma in terms of some, all, or none of the variables Q, a, θ, dθ, and the constants k and π.

Consider a spherical surface of radius R centered on the origin and carrying a uni- form charge density o. Find the electric field a distance z along the z-axis, using direct integration (i.e., not Gauss's Law). Treat the case z R (outside). Express your answers in terms of the total charge q on the sphere. [Hint: Use the law of cosines to write w in terms of R and 0. Be sure to take the positive square root: √(R – z)² is R – z if R > z, and is z — R if R < z.] Now repeat the calculation using Gauss's Law, and show that you get the same answer (although this time much more easily).
