What is the magnitude of the electric charge on the earth

Reference no: EM13674753

Measurements indicate that there is an electric field surrounding the Earth. Its magnitude is about 140N/Cat the Earth's surface and points inward toward the Earth's center.

1. What is the magnitude of the electric charge on the Earth?

2. Is it positive or negative? [Hint: The electric field outside a uniformly charged sphere is the same as if all the charge were concentrated at its center.]
