A graph of the x component of the electric field as a function of x in a region of space is shown in the figure below. The scale of the vertical axis is set by E potential at the origin is 12 V. Exs -Exs 2 3 4 5 6 x (m) (a) What is the electric potential at x = 2.0 m? 35.5 x v (b) What is the greatest positive value of the electric potential for points on the x axis for which 0 x 6.0 m? xs (c) For what value of x is the electric potential zero? m = 47.5 N/C. The y and z components of the electric field are zero in this region. Suppose that the electric
