Final Net Charge for +23.62µC & 12.82 x 10^{14} Electrons

AI Thread Summary
The problem involves calculating the final net charge of an object that starts with a positive charge of +23.62µC after transferring 12.82 x 10^{14} electrons. Each electron has a charge of -1.6 x 10^{-19} C, leading to a total negative charge from the electrons of approximately -20.53µC. To find the final charge, this negative charge is subtracted from the initial positive charge, resulting in a final net charge of approximately +3.09µC. The confusion arises around the application of the formula q=ne and the interpretation of the initial charge. The final charge indicates that the object remains positively charged after the electron transfer.

Homework Statement



An item starts with a net positive charge of +23.62µC. A total of 12.82 x 10^{14} electrons are transferred to the object. What is the final net charge?

a. +228.7µC b. -181.5µC c. -25.67µC d. +181.5µC

Homework Equations



q=ne

The Attempt at a Solution



I'm confused on how to solve this.

I was thinking n=12.82 x 10^{14} electrons, but I don't know which variable +23.62µC would be. Is e supposed to always equal 1.6 x 10^{-19}?
 
Physics news on Phys.org
When you transfer electrons to a positively charged body its net positive charge decreases. If the net negative charge of the transferred electrons is more than the positive charge on the body, the body becomes negatively charged.
Yes. e supposed to always equal 1.6 x 10LaTeX Code: ^{-19}
 
So what am I solving for here? Am I solving for q? Do I need to use the q=ne equation?

so n=12.82 x 10^{14} electrons, and e=1.6 x 10^{-19}. What is 23.62µC?
 
What is the total charge on 12.82X10^14 electrons? It will be negative. From this remove the original positive charge 23.64 micro C. The twill be the remaining charge on the item.
 
Thread 'Voltmeter readings for this circuit with switches'
TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
Thread 'Correct statement about a reservoir with an outlet pipe'
The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
