    What is the excess charge on the surface of the earth?

    Yeah, permittivity constant is 8.85*10^-12.

    What is the excess charge on the surface of the earth?

    Why don't you use the formula for Electric flux? The Net electric flux through surface is basically Electric field * (4pi*(radius of Earth ^ 2)) = excess charge / permittivity constant.
