During a lightning strike, on the order of 10 C of charge is transferred to the ground over a potential difference of 2×108 V. What is the capacitance of the cloud-ground system? How much energy is stored in the system just before the strike? As a check on the order of magnitude of your answer for part B, convert the energy released in the lightning strike into liters of gasoline (gasoline has a stored chemical energy of 36 MJ/liter).
