It's only urgent because you didn't do this earlier....

This question should have been posted in the Homework Help section. As such, we don't do your homework for you. Once you post your aren't at the solution, we can help guide you in the right direction.

To start, what are the relationships between electric field, electric charge, and potential?

UNITS!!!!!

Are the points located 2 microns away from each other, or two light years. It makes a difference.

You need toi show YOUR best effort to solve YOUR homework. Just coming here and asking for someone to solve it for you is not going to get you very far.

I'm not your professor, you don't need to give excuses, just your attempt at a solution.
