1. The problem statement, all variables and given/known data Two spheres are suspended on strings and repel each other. Using the graphing function of your calculator setup and solve a formula to find theta. The length of the rope is 3.0m, q = 1.0e4 and m = .2 kg. 2. Relevant equations F=k*q1*q2/r^2 3. The attempt at a solution Using newton's second law I've tried several times to set up the formula to solve for theta but I am unable. I know that the y component of tensions is equal to the force of gravity. Also that the X component of tension is equal to force caused by the repulsion of the two charges.
