일반물리학 2 — Electric Potential: Problem 11

11 An electron is placed in an xy plane where the electric potential depends on x and y as shown, for the coordinate axes, in Fig. 24-28 (the potential does not depend on z). The scale of the vertical axis is set by \( V_s = 1000 \text{ V} \). In unit-vector notation, what is the electric force on the electron?
