What Q and what R?Would i use the average?

How would i go from U to V? What U would I use?

It wants the V for that point, so where would I go from having the U's of those adjacent to it?

Apparently there is because I typed in 0 and the program said I was wrong.

oh... thank you.

It would make sense that a computable number belongs in a computable set. I would agree.

I found the U's of the sides with dimensions.

In this situation? I don't know if I adequately described it.

Homework Statement There is a 4 cm by 3 cm rectangle with 2.0 nC charges at three corners. I'm trying to find the electric potential of the last corner in V. Homework Equations U=(kQq)/r I think V=(kq)/r I think The Attempt at a Solution I found the U's between the know corners but i don't know...
