Solve the all parts of following question given below:
Question: The earth has a net electric charge that causes a field at points near its surface equal to 150N/C and directed in toward the center of the earth.
Part A: What charge would a human with a mass of 61.0kg have to acquire to overcome his or her weight 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 160m?
Part C: Is use of the earth's electric field a feasible means of flight? Why or why not?
Please show all work and clearly explain each step.
