Why is the following situation impossible? Two identical dust particles of mass 1.00 µg are floating in empty space, far from any external sources of large gravitational or electric fields, and at rest with respect to each other. Both particles carry electric charges that are identical in magnitude and sign. The gravitational and electric forces between the particles happen to have the same magnitude, so each particle experiences zero net force and the distance between the particles remains constant.

5: Two solid spheres of radius R each have a total charge Q. Sphere A is a conductor and sphere B is an insulator with the charge spread out evenly throughout its volume. The spheres are far from each other so they do not influence each other. Compare the magnitudes of the electric fields at T = for each sphere. Specifically, which is larger and why? Are they zero or nonzero? Explain. Similarly, compare the electric fields at r =...
