Physics question help

Two balls of identical mass of 0.421 kg and with identical charges placed on them hang from the ceiling on identical strings of lengths 0.910 m as shown. If the angle with respect to the vertical that the strings form is 27.5 degrees, what is the charge on each ball? Please give your answer in micro-coulomb (i.e. do not enter a unit, but calculate your answer in micro-coulomb).
