What is the value of a charge of a body that carries 20 excess electrons?
I think that the question asks you to pretend that something is negatively charged by 20 electrons. So I think you take the charge of an electron, which is 1.6 x 10^-19, and multiply it by 20. If you do that, the answer is 3.2 x 10^-18.
Please let me know if this is right.
