Given that an electric field of 3×106V/m3×106V/m is required to produce an electrical spark within a volume of air, estimate the length of a thundercloud lightning bolt.

Length, l = 33.4 m

Explanation:

Given that,

Electrical field,

Let the electrical potential is,

We need to find the length of a thundercloud lightning bolt. The relation between electric field and the electric potential is given by :

So, the length of a thundercloud lightning bolt is 33.4 meters. Hence, this is the required solution.

pe = weightxheight = 2000x1000=2,000,000joules

i would say
