What are the correct answers to this Equipotential Contours Homework statement?

Homework Statement

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?

State why you gave the answers that you did so we can help you.

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!
