  1. Feb 27, 2010 #1
    1. The problem statement, all variables and given/known data

    Rearrange F=Kq1q2/r^2 to make K the subject

    2. Relevant equations

    3. The attempt at a solution

    K=Fr^2/q1q2 - is this correct? Sorry Im new to this!! Thanks :)

    If you want to check your answer, just make up values for k, q1, q2, and r and find F. Then use that F along with the same values for q1, q2, and r and see if you get what you assigned to k originally.
