Question

The electric potential in a certain region is given by the equation V(x, y, z) = 3alpha x²y³-2gamma x2y⁴z², where the potential is in volts when positions are given in meters. The constants in this equation are given below.

Alpha = 4.2 V/m⁵

Gamma = 0.51 V/m⁸

Find the magnitude of the electric field at the point (x1,y1, z1)= (-5.0,2.0,1.5) meter in units of Newton's per coulomb.
