4. Having found the voltage difference from knowing the electric field, we can also do the inverse, find theelectric field if we know the voltage as a function of position. Since the inverse of integration isdifferentiation, we have:avEyây'The partial derivative OV/Ox means that to take the derivative with respect to x while treating y and z asconstant. The electric potential in a region of space is given byEx=What is the electric field in this region?avƏx'25yV (x, y, z) = V. ((-)² – 57)avəz
