Am I solving this equation correctly

Coulomb's law I am trying to solve for q

F=K*q1q2/d squared

q1 and q2 are the same so

F=K*q squared/ d squared

you multiple by d squared and you are left with

Fd squared= K*q squared

Now I divide by K

q= sq.rt. of Fd squared/K

Is that correct?

-
Yes correct.

-
Yes. But it's a bit neater to write something like q = sqrt(Fd^2/k)

-
yeah and remember you will get two values of q. +/- sqrt
