In a typical hydrogen atom the electron orbits the proton at a distance of about 0.53x10-10 m.
1. Decide the magnitude and direction of the electric field at this point.
2. Decide the electrical force (magnitude and direction) on an electron at this distance.
3. How does the electrical force compare to the gravitational force among the two particles?
