Consider an electrostatic generating machine that charges an isolated conducting sphere to 19.9 kV relative to a ground (0 V) that is far away. What is the smallest radius (in cm) that the conducting sphere could have, and not produce a discharge in the air surrounding it (which has a breakdown strength of 30 kV/cm)?
