Chapter 23, Problem 051 In the figure a nonconducting spherical shell of inner radius a = 2.32 cm and outer radius b = 2.62 cm has(within its thickness) a positive volume charge density ρ A/r, where A is a constant and r is the distance from the center of the shell. In addition, a small ball of charge q = 45.7 fc is located at that center, what value should A have if the electric field in the shell (a

The figure below shows a non-conducting spherical shell with a charge density of ρ = + 2 x 10-6 C/m^3. If the inner and outer radii of the sphere a = 10 cm and b = 20 cm, respectively, find the electric field strength E as a function of the distance from the center of the sphere's shell r, with r from zero to 30 cm.

A solid sphere of radius a is concentric with a hollow sphere of radius b, where b > a. If the solid sphere has a uniform charge distribution totaling +Q and the hollow sphere a charge of –Q, the electric field at radius r, where r < a, is which of the following, in terms of k = (4π∈0)–1? Choose the correct answer. kQ/b2 zero kQ/a2 kQr/a3 kQ/r2

The figure shows a very large nonconducting sheet that has a uniform surface charge density o = -2.70 µC/m2; it also shows a particle of charge Q = 7.40 µC, at distance d from the sheet. Both are fixed in place. If d = 23.0 cm, at what (a) positive and (b) negative coordinate on the x axis (other than infinity) is the net electric field of the sheet and particle zero? (c) If d = 70.0 cm, at what coordinate is É net = 0? (a) Number Units (b) Number i Units (c) Number i Units >
