Question
Please answer all questions!!!
6.) What net charge would you place on a 113 g piece of sulfur if you put an extra electron on 6 in 1012 of its atoms? (Sulfur has an atomic mass of 32.1 grams per mole.) Give your answer in microcoulombs. Remember that extra electrons result in negative charge!
7.) Common static electricity involves charges ranging from nanocoulombs to microcoulombs. How many electrons are needed to form a charge of -1.19 nC? Give your answer in terms of 1010electrons.
8.) How far apart must two point charges of 70.59 nC (typical of static electricity) be to have a force of 0.86 N between them? Give answer in 10-3 meters.
9.) Suppose a speck of dust in an electrostatic precipitator has 0.619×1012 protons in it and has a net charge of -1.54 nC (a very large charge for a small speck). How many electrons does it have? Give answer in terms of 1012 electrons.
10.) A certain lighting bolt moves 48.6 C of charge. How many fundamental units of charge |qe| is this? Give your answer in terms of 1020.
Explanation / Answer
ACCORDING TO THE CHEGG GUIDELINES I AM ALLOWED TO ANSWER ONLY 1 QUESTION AT A TIME.PLEASE ASK OTHER QUESTIONS SEPERATELY.
10 ) CHARGE = 48.6 C
We know that : q =n * e
n = q/e = 48.6 C / 1.6e-19
n = 3.0375 * 10 ^ 20 electrons =========================answer)
