Consider a uniform electric field E of magnitude E = 7.6 N/C. The line segment connecting points A and B in the field is perpendicular to the direction of the field, while the line segment connecting points C and B is parallel to the field. The line segments have equal lengths of d = 0.51 m. Refer to the figure. 1. Find the potential difference, in volts, between point A and point B.  2. Enter an expression for the potential difference between point C and point B in terms of E and d.  3. Calculate the potential difference, in volts, between point C and point B.
