Question

Electron in a well. Figure 24-57 shows electric potential V alongan x axis. The scale of the vertical axis is set by Vs=8V . Anelectron is to be released at x=4.5cm with initial kinetic energy3.00 eV. (a) If it is initially moving in the negative direction ofthe axis, does it reach a turning point (if so, what is the xcoordinate of that point) or does it escape from the plotted region(if so, what is its speed at x=0)? (b) If it is initially moving inthe positive direction of the axis, does it reach a turning point(if so, what is the x coordinate of that point) or does it escapefrom the plotted region (if so, what is its speed at x=7cm)? Whatare the (c) magnitude F and (d) direction (positive or negativedirection of the x axis) of the electric force on the electron ifthe electron moves just to the left of x = 4.0 cm? What are (e) Fand (f) the direction if it moves just to the right of x=5cm?
