1. The problem statement, all variables and given/known data The charge on two pith balls can be calculated by knowing their masses and observing the angle of separation between the balls. If both balls are equally charged and they are suspended by strings that are 1.0 m long, calculate that charge. 2. Relevant equations F = k q Q / d^2 3. The attempt at a solution fnet=kqQ/d^2 ma=kq^2/d^2 (both q's are the same) Im a bit stuck here because i don't know how to find the acceleration. Thank you!
