Electron in Electric Field

An electron moves in an electric field as a function of position as shown in figure below. Regions of constant electric field are joined by jump discontinuities as shown by the vertical dotted lines.

Useful Info

Express your answers in eV (electron-Volts) rather than converting to joules. (Note that the charge on an electron is -e, so an electron in an electric potential of \(1\)V feels a potential energy of -1 eV. Also note that the potential energy at \(x = 0\) is given.)

Part 1

a. On the second graph, the electric potential at \(x\)=0 is shown. Draw the electric potential for \(x\) from 0 to 3 m.

b. On the lowest graph, draw the electric potential energy as a function of position for an electron experiencing the electric field shown in the figure.

Your file must be a png named ‘Electron’.
