I only want the answer for the try it yourself question.

Two equal-mass small aluminum foil balls A and B have electric charges +q+q (on A) and +3q+3q (on B). (a) Compare the magnitude of the electric force that the foil ball with the smaller charge exerts on the ball with the larger charge (FA on B)(FA on B) to the force that the larger charged ball exerts on the smaller charged ball (FB on A).(FB on A). Justify your answer. (b) If the balls are suspended by equal-length strings from the same point, will one string hang at a greater angle from the vertical than the other? Justify your answer.

Try it yourself Assume that the balls have twice the mass of the balls in the above exercise. By what factor should we increase the charges on the balls so that the angle made by the strings does not change?

    Two balls of identical mass of 0.852 kg and with identical charges placed on them hang from the ceiling on identical strings of lengths 1.510 m as shown. If the angle with respect to the vertical that the strings form is 20.0 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). Two balls of identical mass of 0.852 kg and with identical charges...
