So I am studying Gauss's law and I am a bit confused about something. If I am asked to compute the volume or surface charge density of a solid perfectly conducing sphere with a charge Q and radius r, what is being asked of me? Am I just being asked to compute the volume of a sphere and multiply it by Q? I am not sure. Here is what I would do:
E = Q/(4(pi)(epsilon)(r^2) therefore Q = E/4(pi)(epsilon)(r^2)
Is this correct or is there a difference between charge Q and charge density?
E = Q/(4(pi)(epsilon)(r^2) therefore Q = E/4(pi)(epsilon)(r^2)
Is this correct or is there a difference between charge Q and charge density?
