sorry, here is the full problem...
An insulating solid sphere of radius a has a uniform volume charge density and carries a total positive charge Q. A spherical Gaussian surface of radius r, which shares a common center with the insulating sphere, is inflated starting from r = 0.
(a) Find...
Homework Statement
I have a new question if anyone could help...
The question states:
Find an expression for the electric flux passing through the surface of the Gaussian sphere as a function of r for r < a. (Use epsilon_0 for 0, rho for , Q, a, and r as necessary.)
Find an expression for the...
