If two charged balloons are 10cm apart and they feel a force of electrical repulsion of 20N, what would the force of electrical repulsion become if the balloons were moved apart to a distance of 100cm?

Protons and neutrons are found within the nucleus of an atom

What is the rate of change in a objects position?

Electric field of the earth. 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. (a) what magnitude and sign of charge would a 60-kg human have to acquire to overcome his or her weight by the force exerted by the earth’s electric field? (b) what would be the force of repulsion between two people each with the charge calculated in part (a) and separated by a distance of 100 m? is use of the earth’s electric field a feasible means of flight? why or why not?
