The diagram above is a scalar field showing the electrical potential at several positions in a conducting 2-dimensional plane.
There are two point charges in this plane. What are the coordinates of these charges and their signs?
D6 = negative; M6 = positive
D6 = positive; M6 = negative
A1 = positive; N10 = negative
A10 = negative; N1 = positive
