Air is a non-conductor of electricity, but above certain threshold field $E_{th}$, air becomes ionized and can conduct electricity. This phenomenon is called leakage of charge. For a conducting sphere of radius $R = 10\; cm$, it is known that $E_{th} = 10^8 V/m.$ The maximum potential to which the conducting sphere can be charged in air without the possibility of leakage is
