Common static electricity involves charges ranging from nanocoulombs to microcoulombs. How many electrons must be removed from a neutral object to leave a net charge of 0.500 μC ? Negative charge of an electron = 1.602×10−19 C 2.122×10^12 electrons 3.121×10^12 electrons 8.321×10^12 electrons 4.521×10^12 electrons
