How many excess electrons does an object with a total charge of -1.0 x 10exp-9C have on it? This is approximately the amount of charge involved in commonly encountered static electricity.

• Physics -

Divide the charge by the charge on one electron.

• Physics -

So if one electron is 1.6 x 10 exp -19 C it would be -1.0 x 10exp-9C divided by 1.6 x 10 exp -19 C correct?
