Question

Does earth have an electric field?

Answer 1

Explanation:

The equation of the electric field intensity as.

$\overrightarrow{E}=\frac{q}{4\pi {\epsilon }_0{r}^2}$

Where ${\epsilon }_0$ is the permittivity of the free space and $r$ is the separation distance

Therefore the electric field $\left(\overrightarrow{E}\right)$ of the earth is the consequence of the earth having a net negative charge $\left(q\right)$ due to the charge separation distance $\left(r\right)$ between the ground and the atmosphere.

Hence, the earth has an electric field.
