I am having trouble doing this question.
Measurements indicate there is an electric field surrounding the earth. Its magnitude is about 100 N/C at the Earth's surface and points to the centre of the earth. What is the magnitude of the electric charge on the earth? Is it positive or negative?
(Hint: The electric field caused by a uniformly charged sphere is the same as if the entire charge were concentrated at its centre)
