1. The problem statement, all variables and given/known data two pith balls are suspended on a wooden dowel and have the same origin point. the two balls are push away from each other and are equally negatively charge. the string have the lenght L and the two strings form angle (theta). knowing Fg= Gm1m2/r^2 Fe= kq1q2/r^2 2. Relevant equations using the electrostatic constant k dervie the formula below. Q= 2Lsin(theta) x square root of [mgtan(theta)/k] 3. The attempt at a solution i found out that Fe= mgtan(theta) and Fe -Ft is the horizontal component. then i dont know wat to do after.
