1. The problem statement, all variables and given/known data To find the amount of static charge on the balls using coulomb's law and the concepts of equilibrium. r = 3.3 cm m1 = .085g m2 = .085g [tex]\vartheta[/tex] = 9.4[tex]\circ[/tex] 2. Relevant equations F = K(q1)(q2)\r2 3. The attempt at a solution I legitimately have no clue how to do this other than the fact that r = 9.4... Any tips/help will be appreciated.
