V PartA In a certain region of space the electric potential is given by V : +szy _ Bwyz, where Calculate the magnitude of the electric field at the point in the region that has cordinates m = 1.60 m, y = 0.400 m, and z = 0. A = 5.00 V/m3 and B = 8-00 V/m3. Express your answer with the appropriate units. E = Value Units Muest Answer V PartB Calculate the direction angle of the electric field at the point in the region that has cordinates as = 1.60 m, y = 0.400 m, and z = 0. Express your answer in degrees. I El o rt 0 =2 0 , measured counterclockwise from the positive z axis in the my plane Muest
