(a) Calculate the ration of the electric force over the gravitational force ( FE FG ) between the electron and the proton from question 3. Include the steps. (b) Does the result of part (a) make sense? Explain in terms of the relative strengths of the four fundamental forces (interactions) of nature. [Refer to the textbook for more information on the fundamental forces of nature.] 5. The arrows representing the electric field in the simulation used in Part 2 represent the actual electric field at different positions, and NOT the electric field lines. How do the electric field lines and the electric field relate to each other? [Refer to the lecture slides and the textbook for related information.] AGB_DC
