1. The problem statement, all variables and given/known data distance between two electrical charges q1=10nC, q2=16nC is 7mm , what force will act at third charge q3=2nC, placed between the first two charges 3mm far from the smaler charge and 4 mm far from the larger charge. 2. Relevant equations Fc=k*|q1||q2|/r2 3. The attempt at a solution F1,3=0,02(N) F2,3=0,018(N) then F=F1,3-F2,3=0,02N-0,018N=0,002N=2(mN) am I right?
