Lightning occurs when there is a flow of electric charge (principally electrons) between the ground and a thundercloud. the maximum rate of charge flow in a lightning bolt is about 20,000c/s; this lasts for 100μs or less. how much charge flows between the ground and the cloud in this time?

2C  charge will flow from ground and cloud

Explanation:

We have given rate rate of flow of charge

Time is given as

WE have to find the how much charge flows between the ground and cloud in this time

So the charge flow is given by

So 2C  charge will flow from ground and cloud

come closer and become far apart and become steam/gas

i don't know that i agree with that but what's the question ?
