According to the Bohr model of the hydrogen atom, the electron orbits the proton at a radius of 52.9x10^-12 m. a. Show that the force of gravity (Fg) that exists between the electron and proton is negligible compared to the electric force (Fe).
b. Determine the linear velocity (vt) of the electron as it orbits.
c. Determine the angular velocity (Ï) of the electron
d. Determine the number of seconds it takes for the electron to complete one orbit

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?
