Solution

The correct option is A True
The potential difference created between the top of the atmosphere and the surface of the Earth is approx. 400 kV, but potential difference between lower part of a thunderstorm and the surface of the Earth is 20-100 MV. The statement is true.

. The potential difference of 400 kV between the top of the atmosphere and the surface results (due to the low conductivity of the lower atmosphere) in a current of only 1800 A over the entire globe. If there were no mechanism of sustaining atmospheric electric field, how much time (roughly) would be required to neutralise the earths surface? (This never happens in practice because there is a mechanism to replenish electric charges, namely the continual thunderstorms and lightning in different parts of the globe). (Radius of earth =
