Does Earth's Inward Electric Field Indicate Its Charge Polarity?

[thisisfudd]

So, Measurements indicate that there is an electric field surrounding the Earth. Its magnitude is about 150 N/C at the Earth's surface and poitns inward toward the Earth's center. What is the magnitude of the electric charge on the Earth? Is it positive or negative?

I got the answer, but is it negative or positive?

If the vector \vec{E} is pointing toward the center then the charge is negative.

Based on the information provided, the magnitude of the electric charge on the Earth cannot be determined. The electric field is a result of both positive and negative charges, and their exact distribution cannot be determined without further information. Additionally, the direction of the electric field does not necessarily indicate the polarity of the charge. Therefore, the magnitude and polarity of the electric charge on the Earth cannot be determined solely based on the given information.
