Question

Two identical balls balls P and Q, each of mass 0.20 g, carry identical charges and are suspended by two threads of equal length. The balls position themselves at equilibrium such that the angle between the threads is 60 degrees. If the distance between the the balls is 0.5m, find the charge on each of them. Take g=9.8m/s^2
