Homework Statement
Electric Field of the Earth. The Earth has a net electric charge that causes a field at points near its surface equal to 153 N/C and directed in toward the center of the earth.
1. What charge would a human with a mass of 58.0 kg have to acquire to overcome his or her weight by the force exerted by the Earth's electric field?
2. What would be the magnitude of the repulsive force between two people each with the charge calculated in part (a) and separated by a distance of 120 m?
Homework Equations
[tex] E = \frac{1}{4*pi*e_o}*\frac{q}{r^2*\vec{r}}[/tex]
[tex] G = 9.81 & m/s [/tex]
The Attempt at a Solution
I couldn't find any relevant information in the electric field section that I could map to this problem to help me solve it. Does anyone have a suggestion on where to start?
