four spiritually charges is given by Coolers Law that is a physical to K Times key. One killed, two derided by our square R is the distance between them. So substituting values for K that is eight or 99 times gentle power. Nine time 7.5 Full time student power minus lay does four times to tend to power minus nine. Divided by our reach is 1.80 swear. Excuse us. The force off eight, Foreign 74 times 10 to the power eight Newton. What be this force will be a pulse you. But if bolt's you because both charges are a positive positive, so Sam charges will repel each other.
