    Balloon Electrons
AI Thread Summary
To calculate the charge on a balloon after losing 19,000 electrons, one must use the equation Q = Ne, where N is the number of electrons and e is the charge of an electron (-1.6 x 10^-19 C). Removing electrons results in a positive charge, so the answer cannot be negative. The correct calculation involves multiplying 19,000 by the absolute value of the electron charge, yielding 3.04 x 10^-15 C. To convert this to microcoulombs, divide by 10^-6, resulting in a final charge of 3.04 x 10^-9 microcoulombs. Proper conversion is crucial to avoid errors in the final answer.

[SOLVED] Balloon losing electrons

Homework Statement


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.


Homework Equations


I THINK Q = Ne


The Attempt at a Solution


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!

You are doing your conversion backwards! Divide by 10^-6.
 
oh god.thanks a bunch
 
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
