'2-11 The dielectric strength of air (i.e. the electric field above which the air becomes conducting) is 3 X 10 V/m; () What is the highest possible potential of an isolated spherical conductor of radius 8 cm? (b) What is the radius of a spherical conductor which could hold 1 coulomb of charge?'

Conducting Sphere A conducting sphere of radius $10 \mathrm{~cm}$ has an unknown charge. If the electric field $15 \mathrm{~cm}$ from the center of the sphere has the magnitude $3.0 \times 10^{3} \mathrm{~N} / \mathrm{C}$ and is directed radially inward, what is the net charge on the sphere?
If the electric ficld strength in air exceeds $3.0 \times 10^{6} \mathrm{N} / \mathrm{C}$ , the air becomes a conductor. Using this fact, determine the maximum amount of charge that can be carricd by a metal sphere 2.0 $\mathrm{m}$ in radius. (See the hint in Problem 40.)
