Two balls of identical mass of 1.152 kg and with identical charges placed on them hang from the ceiling on identical strings of lengths 1.310 m. If the angle with respect to the vertical that the strings form is 24.5 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).
