In lightning storms, the potential difference among the Earth and the bottom of the thunderclouds can be as high as 34,000,000 V. The bottoms of thunderclouds are usually 1500 m above the Earth and can encompass an area of 105 km2. For the purposes of this trouble, model the Earth-cloud system as a huge capacitor.
(i) Compute the capacitance of the Earth-cloud system.
(ii) Compute the charge stored in the ‘capacitor’.
(iii) Compute the energy stored in the ‘capacitor’.
