Electron in a well. Figure 24- 65 shows electric potential V along an x axis. The scale of the vertical axis is set by Vs 8.0 V. An electron is to be released at x ! 4.5 cm with initial kinetic energy 3.00 eV. (a) If it is initially moving in the negative direction of the axis, does it reach a turnin
