Thank you

checked it 5 timed every time the answer was 7.1904 N After that i went to this page: http://www.endmemo.com/physics/coulomb.php and the answer there was also 7.1904 N

I see now, I ment μC not mC sorry.

Hi, Can someone help me with this question? I understand Coulomb's law but i want to know if I am doing it right. So the charge of Q1= 2 mC Q2= 1 mC And R= 5 cm (0,05m) This is how i solved it. F= K(8,988x10^9) x (2x10^-6)x(1x10^-6) / (0,05m)^2 F= K(8,988x10^9) x 8x10^-10 F= 7.1904 N...
