If the electric field strength in air exceeds 3.0*106 N/C, the air becomes a conductor. Using this fact, decide the maximum amount of charge that can be carried by a metal sphere 2.4 m in radius. (Hint: Review properties of conductors in electrostatic equilibrium. Too, Use that the points on the surface are outside a spherically symmetric charge distribution; the total charge might be considered to be located at the center of the sphere.)
