[SOLVED] Balloon losing electrons
You have a neutral balloon. The charge of an electron is -1.6x10^-19C.
What is its charge after 19000 electrons have been removed from it? Answer in units
of microcoulombs.
I THINK Q = Ne
This question should be very easy but for some reason I am hesitant to answer it any more because I lose points every time I do it. I understand that when you remove electrons from an object the particle becomes positively charged, so this rules out a negative answer.
I tried 19000 x 1.6x10^-19 and submitted that answer = 3.04x10^-15
I also tried 19000 x 1.6x10^-19 x 10^-6 ( converting to microC ), and that answer was still wrong = 3.04x10^-21
What am I doing wrong? This seems too simple ... :(
Thank you!
