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 20,000 C/s this lasts for 100 μs or less.1. How much charge flows between the ground and the cloud in this time? (Q= ? C)2. How many electrons flow during this time? (n_e = ?)

a

 The  charge is  

b

The number of electrons  

Explanation:

From the question we are told that

    The  maximum rate of charge flow is  

Here  I means current

    The time interval is

Generally the amount of charge is mathematically represented as

=>      

=>    

The number of electrons that flow during that time is evaluated as

Here e is the charge on a single electron with value

So

i think the answer would be b
