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?

  • physics -

    (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
