- A net flux of 6.75×10^4N⋅m2/C passes inward through the surface of a sphere of radius 5.25 cm. a. What is the net charge, in coulombs, contained within the sphere? b. Which statement best describes the distribution of the charge inside the sphere? All of the charge is concentrated in a point charge. The flux indicates the net charge enclosed in the surface, but it yields no information about the distribution of the charge. The charge can be distributed in many different ways, but the distribution must be spherically symmetric. Both positive and negative charges are contained within the sphere, but most of the charges cancel yielding the net charge obtained in the previous step. The charge is uniformly distributed throughout the volume of the sphere. The charge is distributed over a thin spherical shell within the sphere.Three identical charges (q = -6.3 µC) lie along a circle of radius 2.3 m at angles of 30°, 150°, and 270°, as shown in the figure below.
