One way to write Coulomb's law is F=(k lQql)/(r^2) where F is the magnitude of the electric force, k is a constant, Q and q are the two electrical charges and r is the distance between them. Solve Coulomb's law for r.

Best ResponseYou've already chosen the best response.0Multiply both sides by r^2, to get it on the left. Divide both by F, to get it on the right. r^2 = etc. r = sqrt(etc.) you should finish it.

Best ResponseYou've already chosen the best response.0i did it, and it gave me r=+,(sqrt(k(Qq))/(sqrt(F)), however, the system still reads it as incorrect, is there i'm missing with the absolute value of “Qq”？

Best ResponseYou've already chosen the best response.0r cannot be negative as it is a distance. Did you use Qq or (Qq)? Former is needed.

Best ResponseYou've already chosen the best response.0i can not use capital Q, because wileyplus(the software) do not allow me to.
