Question

In a certain region of space the electric potential is given by V=+Ax²y-Bxy², where A= 5.00 V/m³ and B= 8.00 V/m³.

Part A Calculate the magnitude of the electric field at the point in the region that has coordinates x= 1.10 m, y= 0.400 m, and z= 0. Express your answer to three significant figures and include the appropriate units.

Part B Calculate the direction angle of the electric field at the point in the region that has coordinates x= 1.10 m, y= 0.400 m, and z= 0. Express your answer in degrees ⁰, measured counterclockwise from the positive x-axis in the xy plane.
