A group of charges produces an electric field. The potential along the x-axis is given by the following: V(x) = 5.7x – 1.89x² – 3.51, where Vis in Volts and x is in meters along the axis. Find the value of the electric field E, in N/m, along the x-axis at x = 0.807 m. The sign will indicate the directional field.
