Two particles move along two different trajectories in an electric potential given by v(x, y) k x y, where k is a constant. a contour plot of the potential is shown (lighter color means higher potential, darker means lower potential). particle a, with charge q 6c takes the straight dashed line. particle b, also with charge q 6c takes the solid line curved path. the initial position is (x, y) (0.2, 0.2) m. the final position is (x, y) e (0.2, 0.7) m. which particle gains more electric potential energy? initial a) particle a b) particle b c) both gain the same amount of potential energy d) not enough information

Materials will have different energies associated with the electrons inside them. this is related to how strongly bound they are by their work function. if we sandwich a material with a very low energy between two materials with a high energy, we create a trap for an electron. if this trap is very narrow in one direction in comparison to the others, this is approximately a 1-dimensional box that confines the electron. what is the lowest energy of an electron in the box if the thinnest direction across the materials is 4.81 nm?
