35. The electric field (along some axis) is the (negative of the) derivative of the potential V with respect to the corresponding coordinate. In this case, the derivatives can be read off of the graphs as slopes (since the graphs are of straight lines). Thus, E x = d V d x = © ¨ § ¹ ¸ · 500 V 0.20 m = 2500 V/m = 2500 N/C E y = d V d y = © ¨ § ¹ ¸ · 300 V 0.30 m = –1000 V/m = –1000 N/C . These components imply the electric field has a magnitude of 2693 N/C and a direction of –21.8º (with respect to the positive
