Problem 2: The force between a positively charged foam cup and a positively charged metal sphere is 5.2 x 10-4 newtons. The charge on the cup is 7.2 x 10-6 coulombs, and the charge on the metal sphere is 6.8 x
10-6 coulombs. What is the distance between the two objects? (k = 9.0 x 10° newtonmeters 2 coulombs?)
Part C: Modify the force equation to solve for the distance, r. Do not enter any numbers. Just express r as an equality
in terms of the other variables. Use your keyboard and the keypad to enter your answer. Then click Done.
