A +5×10-9 C point-charge is in static equilibrium at the center of a conducting spherical shell, which has an inner radius of 0.3 m and an outer radius of 0.5 m. The shell itself carries a net charge of -6×10-9 C. What is the magnitude of the electric field immediately outside the outer surface of the shell, with unit in N/C? Note that magnitude is positive.
