Solve the all parts of given problem:

Problem: The planet Earth actually has a net electric charge! This charge creates an electric field at points near the surface of the Earth equal to 150N/C and directed in toward the center of the planet.

Part A: What charge would a person with a mass of 65.0kg have to acquire to be suspended in the air by the force exerted by the Earth's electric field?

Part B: 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 110m?
