1. The problem statement, all variables and given/known data Two uniformly charged spheres are suspended by strings of length L from vertically adjustable supports. The spheres are in static equilibrium. The angles with respect to the vertical are Q=14.9°, and T=20.7°. The tension in the string supporting sphere Z (Z with respect to angle T, W is the other sphere and hangs with respect to angle Q) is 2.41E-5 N. Calculate the tension in the other string. 2. Relevant equations Fe = k (q1 * q2 / (r) ^ 2) Fg = mg 3. The attempt at a solution Alright, here is a brief overview of what I have done. I first recognized that the system was in static equilibrium. Thus, for each sphere I wrote equations representing the force components, and set each equation to zero. Each sphere operates under the same conditions. Sphere Z lies to the left (T is force due to tension, Fe is force due to Electric repulsion) Tx = Tcos∅ Ty = Tsin∅ T = 2.41E-5 N 0 = Tx - Fe 0 = Ty - mg Sphere W lies to the right: Tx = Tcostheta Ty = Tsintheta 0 = -Tx + Fe 0 = Ty - mg So, I recognize that in each case, the x-component of the tension in each string is equivalent. This makes sense because the forces on each sphere with respect to the x-axis are due to the electric force. This force has an equal and opposite effect. I cannot figure out how to find the total tension in the second string, even though I know the x component etc. Any help in progressing from this point would be greatly appreciated.
