A uniformly charged conducting sphere of 1.2 m diameter has a surface charge density of 7.1 µC/m2. (a) Find the net charge in coulombs on the sphere. (b) What is the total electric flux leaving the surface of the sphere?

(a) Multiply the surface charge density by the sphere area, 4 pi R^2 = pi D^2 = 4.52 m^2.
(b) Use Gauss' Law.
Total flux out = Q/epsilono
The units are (Newtons/Coulomb)* m^2
epsilon0 = 8.85*10^12 C^2/n*m^2
