Answer:
Length, l = 33.4 m
Explanation:
Given that,
Electrical field, [tex]E=3\times 10^6\ V/m[/tex]
Let the electrical potential is, [tex]V=10^8\ V[/tex]
We need to find the length of a thundercloud lightning bolt. The relation between electric field and the electric potential is given by :
[tex]V=E\times d\\\\d=\dfrac{V}{E}\\\\d=\dfrac{10^8}{3\times 10^6}\\\\d=33.4\ m[/tex]
So, the length of a thundercloud lightning bolt is 33.4 meters. Hence, this is the required solution.
