The electric potential in a region is given by V = 2.0xy - 3.0zx + 5.0y^2, with V in volts and the coordinates in meters.
Part a:
Find the potential of the electric field at the point x = 0 mm, y = 0 mm, z = 0 mm.
Part b:
Find the components of the electric field at the point x = 0 mm, y = 0 mm, z = 0 mm.
