thank you collinsmark! i was using the wrong formula. instead of using the unit vector i was just using the difference between the 2 vectors. I think once i correct that it should come out okay. Thank you again, i had spent a total of bout 3 hours on this. it's a lot easier than i made it

honestly my professor did not give me very much direction with this and the math is something i have not taken yet. with the info that i had i thought that i would have to find the force from the 5C charge and the 6C charge on the 7C charge and then add them up. When i do this i get odd answers

A 5C point charge located at (2m, 3m, 4m) and a 6C point charge located at (4m, 3m, 2m) together exert a net force on a 7C point charge located at (2m, 4m, 3m) is most closely represented by... (a) k(-6i + 15j - 10k) N (b) k(-8i + 13j - 12k) N (c) k(7i + 14j - 11k) N (d) k(7i - 14j - 11k)...
