Question
I'm stuck on this problem:Suppose you had two small boxes, each containing 1.00 g ofprotons. If one were placed on the moon by an astronaut and the otherwere left on the earth, and if they were connected by a very light(and very long!) string, what would be the tension in the string?Express your answer in newtons and in pounds. No longer need help on thisportion. Do you need to take into account the gravitational forces ofthe earth and moon on the protons? Why? No, because the distance make the forcenegligible? What gravitational force would each box of protons exert onthe other box? No longer need help on thisportion. Thanks in advance for the help. I'm stuck on this problem:

Explanation / Answer
m = 1.00 g number of protons N = 1.00 g/(1.67*10-27 kg) =5.988*1023 q = Ne = 9.581*104 C distance r = 3.84*108 m electric force Fe = kq2/r2 = 560N gravitational force between 2 boxes Fg =Gm2/r2 = 4.52*10-34 N tension T = Fe = 560 N
