A Gaussian surface encloses two charges. The total electric flux through the Gaussian surface is 8.3 x 106 N m2/C. If one of the charges is -14.9 micro-Coulombs and the magnitude of the electric force between them is 2.76 Newtons, what is the distance between the charges in meters?

Use the total flux and Gauss' law to get the total charge inside the enclosing surface.

From the value of one charge, and the sum from the first step, get the other charge.

From the force and the values of the two charges, get the separation R using Coulomb's law.
