Hello everyone! I'm having a problem with this question from my book...

How many electrons have been removed from a positively charged electroscope if it has a net charge o 7.5x10^-11 C?

Can someone explain to me how to solve this problem>?
Thank you very much!

Hello,

What is the charge of a single electron? What about two? What about an arbitrary number call it "x" electrons?
 


What's the charge on each electron?
 


it's 1.6x10^-19 C

so does it mean that 7.5x10^-11/ 1.6x10^-19 is the number of electrons?
 


oh i think i got it! thank you so much!
