AI Thread Summary
The discussion centers around the correct answers to an Equipotential Contours homework assignment, where participants analyze the potential energy and charge relationships. Key points include the understanding that the closest contour lines indicate the largest charge, and the importance of considering both the magnitude and sign of charges when determining potential energy. There is confusion regarding the accuracy of specific answers, particularly the interpretation of charge signs and their implications on potential energy. Participants suggest that further opinions may clarify uncertainties, and one user ultimately resolves their confusion regarding the relationship between potential energy and charge. The thread emphasizes the need for careful analysis of charge signs in relation to electric potential.

2. Relevant thoughts

Here, I numbered them down and put why I though those answers were what I have above

1- since 0V, its PE is zero
2- Closest contour lines, largest charge
3- Q1 is farther back from 0v, making it the largest negative
4- above 0V so it has a positive PE
5- Past 0V so its a positive charge
6- I has a higher electrical potential since its closer tot he positive charge

The Attempt at a Solution



You can see my attempt above...im really not sure at all what one is wrong, and why?

Wrote them above.
 
You say #2 is the largest magnitude charge, which ignores signs. This part looks right. But another one is not. Look at the sign of q2 again...

even if number three was true, its still not all right?

It looks like it should be. I don't see any errors that stick out at the moment. If you want to be really sure, you could wait for some other people to give their opinion.
 
I know its not right because with it marked true, it was my very first response (the above answers with 3 being true.) I thought that was right to begin with but its not.
 
How is the potential energy of a charged particle related to the particle's charge and the electric potential at the particle's location?

Which number is lower, 2 or 3 ?
 
SOLVED! Thanks!
