Two small identical balls, each of mass ...

Two small identical balls, each of mass 0.20 g, carry identical charges and are suspended by two threads of equal lengths. The balls position themselves at equilibirum such that the angle between the threads is `60^(@)`. If the distance between the balls is 0.5 m, find the charge on each ball.
