Calculate the net charge on a substance consisting of a combination of 2.8 × 1013 protons and 7.6×1013 electrons. The elemental charge is 1.6 × 10−19 C. Answer in units of C.
Since the charge is negative for electrons and positive for protons just take the difference in the numb ers and multiply by the size of the charge:
net charge = (2.8 - 7.6)*1013*1.6*10-19 C (You can crunch the numbers) Because there are more electrons than protons the net charge is negative.
