A 0.060-kg ball with charge +3.0 × 10^-6 C hangs from a 0.50-m-long string at an angle of 53° below the horizontal. The string is attached at the top on the wall above a second charged object, as shown in (Figure 1) .

A.) Determine the charge on the second object.

B.) What others quantities can be determined using this information?
