The electric potential at a certain point is given by v(x, y, z)= (-4.22 v/m4)x2y2 + (2.60 v/m6)xy4z - (2.11 v/m4) z3y. determine the unit vector form, e = [(+/-abc v/m)i + (+/-def v/m)j + (+/-mp. n v/m)k], of the electric field e at the point (-1.7 m, 2.8 m, -1.5 m) to give that potential. give the x component of electric field in the form x component = "+/-abcd" v/m. give the y component of the electric field in the previous problem. use the format "+/-cdef" v/m for your answer. give the z component of the electric field in problem 9a. use the format "+/-def" v/m.
