Use the worked example above to help you solve this problem. The electron and proton of a hydrogen atom are separated by a distance of about 5.72 multiply. gif 10-11 m at some instant. (a) Find the magnitudes of the electric force and the gravitational force that each particle exerts on the other, and the ratio of the electric force, Fe, to the gravitational force, Fg.
Fe= N
Fg= N
Fe/Fg=
(b) Compute the acceleration caused by the electric force of the proton on the electron. Repeat for the gravitational acceleration.
ae= m/s2
ag= m/s2

What do you need on

Is a  vector quantity  that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.
