Hello, I am pretty new to physics. I have no formal education on physics, and I have been studying it on my own out of curiousity and fascination. Please correct me if anything that I say is wrong and assume I know nothing. Math is also not my strongest skill, but I am trying to become better. For the past couple of days, I have been working with Coulomb's Law. From my understanding the formula used is : (k) q1q2/r^2. I feel pretty comfortable with the formula and I have been doing some practice problems and getting them correct. In all of the questions though, q1 and q2 are given to me. I would like to know how to find the value of "q" without it being given to me. If I were to construct my own experiment and put 2 charges at a certain distance from eachother, how would I go about finding the value of the charges? Thanks!
