Homework Statement
Assume that you have a configuration of conductors with varying electric potentials applied to each. You make the following measurements of the values of the electric potential at different points in a two dimensional grid:
X = 0.0 cm Y = 0.0 cm V = 2.0 volts
X = 2.0 cm Y = 0.0 cm V = 2.25 volts
X = 0.0 cm Y = 2.0 cm V = 2.0 volts
What are the values of the x and y components of the electric field at the origin (Ex and Ey at (x, y) = (0,0))? Express the results in SI units.
