[SOLVED] Balloon losing electrons 1. The problem statement, all variables and given/known data 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. 2. Relevant equations I THINK Q = Ne 3. The attempt at a solution This question should be very easy but for some reason Im 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!
