Question: Before a lightning strike can occur, the breakdown limit for damp air must be reached. If this occurs for an electric field of 3.33

Before a lightning strike can occur, the breakdown limit for damp air must be reached. If this occurs for an electric field of 3.33 × 105 V/m, what is the maximum possible height above the Earth for the bottom of a thundercloud, which is at a potential 1.00 × 108 V below Earth's surface potential, if there is to be a lightning strike?
