Question 61

Regarding the Earth and a cloud layer 800 m above the Earth as the "plates" of a capacitor, calculate the capacitance if the cloud layer has an area of 1.0 km². If an electric field of 2.0 × 10⁶ N/C makes the air break down and conduct electricity (lightning), what is the maximum charge the cloud can hold?
