I have 2 equally charged pith balls suspended by a string repelling eachother at a 28 degree angle. I know that Tension, Gravity, and the electostatic force are all acting. I found tension by creating a force diagram. T= cos14mg. I also found g=mg. I'm having trouble finding out what the electrostatic force would be based on tension and gravity.
The Attempt at a Solution
I believed that Fe= Fg-T, is this correct?
