Electrons Charge

  1. Jan 30, 2006 #1
    I have a question that i can't figure out, if a sphere is charged with electrons to -1 x 10^-5 C. The charge of an electron is -1.6 x 10^-19 C. How many electrons are there on the sphere?

    I simply divided the electron charge by the charge of the sphere but it says i'm wrong. Is the problem me or the computer?

    That's how you're supposed to do it. You should get something like 6 times 10^13.
