1. The problem statement, all variables and given/known data Two small spheres with mass m = 14.3 are hung by silk threads of length L = 1.26 from a common point. When the spheres are given equal charges, so that , each thread hangs at an angle [tex]\theta[/tex] = 22.0 from the vertical. A. Draw a diagram showing forces on the left sphere. B. Find the magnitude of q. 2. Relevant equations Fe = k |q1||q2| / r2 3. The attempt at a solution Part A. I drew three forces on the left sphere. I have the force of gravity, pointing straight down from the shpere. The tension force point along the length of the thread, away from the shpere. And the Electron force pointing directly to the left. I drew the Fe pointing away because I figured both spheres have the same charge since they are being repelled apart. This answer is wrong but I am not sure why. Part B. I used the sum of forces. Fx = Tx - mg = 0 Tx = mg = 0.140 Fy = Ty - Fe = 0 Ty = Fe I calculated Ty = 1.17 Using that I found q 1.17 = kq2 / (0.944)2 q = 1.08 * 10-5 This was also wrong. Any help will be appreciated. Thank You.
