In the figure below, equipotential lines are shown at 1-m intervals. Suppose that V1 = 5 V, V2 = 10 V, V3 = 15 V, V4 = 20 V, and V5 = 25 V. 1) What is the electric field at point A? Enter a positive value if the electric field points in the +x direction and a negative value if the electric field points in the -x direction. (Express your answer to two significant figures.) 2) What is the electric field at point B? Enter a positive value if the electric field points in the +x direction and a negative value if the electric field points in the -x direction. (Express your answer to two significant figures.)
