(14%) Problem 7: The electric potential in a certain region is given by the equation V(x,y,z) = 3ax y' - 2yx y z where the potential is in volts when the positions are given in meters. 25% Part (a) Write an equation for the x-component of the electric field. Ex=- 6axy' + 4yxy4z2 - Correct! 25% Part (b) Write an equation for the y-component of the electric field. Ey =- 9ax2 y2 + 8 yx2 3 z2 . Correct! 25% Part (c) Write an equation for the z-component of the electric field. Ez = 4yx yaz Correct! A 25% Part (d) The constants in this equation are a = 4.7 V/m and y = 0.76 V/m . Using this information, calculate the magnitude of the electric field at the point (x1,)121) = (-5.0, 2.0, 1.5) m in units of newtons per coulomb.
