The electric field everywhere on the surface of a charged sphere of radius 0.260 m has a magnitude of 545 N/C and points radially outward from the center of the sphere.
(a) What is the net charge on the sphere?

    Use Gauss' Law.
    The total flux is
    4*pi*R^3 *E

    Gauss' Law tells you how to relate the flux to the total charge.

    Flux = Q/epsilon0

    epsilon0 = 8.854*10^-12 C^2/(n*m^2)

  • typo I think -

    4*pi*R^2 *E

    Yes, Damon is right. Typo exponent error. Thanks for catching it, DC
