1. The problem statement, all variables and given/known data A charged pith ball (mass = 2 g) is brought close to an identical, equally charged pith ball that's suspended from a thread. When the pith balls are 3.8 cm apart, the thread sits in equilibrium at 14 degrees from vertical. What's the charge on each of the pith balls? and Calculate the deficit/excess electrons 2. Relevant equations Coulomb's Law 3. The attempt at a solution Ok, I know this is already wrong coz I'm getting an invalid answer but I don't rly know how to approach the question... So, I assumed that the balls have equal charge and the force = 0 so... q=square root of (Fr^2/k) Please HELP ME!
