The electric potential in a certain region of space is given by V(x,y,z) = ?xy + ?, in units of volts, where ? = 3.10 V/m2 and ? = 6.06 V are constants.
What is the x-component of the electric field at a point P = (5.00, 2.00, 3.50), where the coordinates are given in meters?
What is the magnitude of the electric field at the same point?
