37. 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, 500 V 2500 V/m 2500 N/C 0.20 m 300 V 1000 V/m 1000 N/C. 0.30 m x y V E x V E y ∂− ⎛⎞ =− = = ⎜⎟ ⎝⎠ These components imply the electric field has a magnitude of 2693 N/C and a direction of –21.8º (with respect to the positive x axis). The force on the electron is given by
