Four identical metallic objects carry the following charges: +5.4 µC, +5.4 µC, -7.0 µC, and -1.6 µC. The objects are brought simultaneously into contact, so that each touches the others. Then they are separated.
a) What is the final charge on each object?
___ µC
b) How many electrons (or protons) make up the final charge on each object?
