Answer:
33.3 m
Explanation:
The relationship between voltage difference and electric field is given by:
[tex]E=\frac{\Delta V}{d}[/tex]
where
E is the electric field strength
[tex]\Delta V[/tex] is the potential difference
d is the distance between the two points considered
For the lightning, we have:
[tex]\Delta V= 10^8 V\\E= 3\cdot 10^6 V/m[/tex]
Substituting into the formula, we find the length of the lightning bolt:
[tex]d=\frac{\Delta V}{E}=\frac{10^8}{3\cdot 10^6}=33.3 m[/tex]
