Question

I need help with part C .

The earth has a net electric charge that causes a field at points near its surface equal to 150 N/C and directed in toward the center of the earth. What charge would a human with a mass of 60.0 kg have to acquire to overcome his or her weight by the force exerted by the earth's electric field? Q = -3.92 C 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 100 m? F = 1.38 times 10^7 Is use of the earth's electric field a feasible means of flight? Why or why not? Essay answers are limited to about 500 words (3800 characters maximum, including spaces) 3681 Character(s) remaining a filed is not a source of energy but potential state energy and the earth does not have a continuous electric filed.

Explanation / Answer

part C)

NO, the earth's electric field is not feasible means of flight because force due to the earth or force between the man and earth is large, it will direct an objects(man) into the space.
