Chapter 2, Problem 2.15P

A spherical volume having a 2-/μm radius contains a uniform volume charge density of 105 C/m3. (a) what total charge is enclosed in the spherical volume? (b) Now assume that a large region contains one of these title spheres at every corner of a cubical grid 3 mm on a side and that there is no charge between the sphere. What is the average volume charge density through out this large region?

In the figure particles 2 and 4, of charge -e, are fixed in place on a y axis, at y₂ = -8.38 cm and y4 = 4.19 cm. Particles 1 and 3, of charge - e, can be moved along the x axis. Particle 5, of charge +e, is fixed at the origin. Initially particle 1 is at x₁ = -8.38 cm and particle 3 is at x3 = 8.38 cm. (a) To what x value must particle 1 be moved to rotate the direction of the net electric force Fnet on particle 5 by 30° (b) With particle 1 fixed at its new position, to what x value must you move particle 3 to rotate back to its original counterclockwise? direction?

A negatively charged (-121 uC) block is sitting on a frictionless, flat surface. This 12 kg block is attached to a vertical wall with a horizontal, 0.39 m long string that is under a tension of 100 N. Embedded in the wall (on the other side of the string) is another charge. What is the charge of this embedded charge in the wall? Assume that the block is stuck in place.
