Coloumbs Law & Charges. Please help! :( 1. The problem statement, all variables and given/known data A charge of +2.0 nC and a charge of +8.0 nC are separated by 36.0 cm. Find the equilibrium position for a −2.0 nC charge as a distance from the ﬁrst charge. Answer in units of cm 2. Relevant equations q/r^2 3. The attempt at a solution I really have no idea how to even start. We just started learning about charged in physics and our teacher hasn't taught us a whole lot (yet we still have to do this homework by ourselves). I just need to understand how to do these problems, and any help would be more than appreciated. Thank you so much and I apologize for not having more information to give!
