Electron in a well figure shows electric potential V along an x axis. The scale of the vertical axis is set by Vs = 8.0V. An electron is to be released at x = 4.5 cm with initial kinetic energy 3.00eV.

(a) If it is initially moving in the negative direction of the axis, does it reach a turning point (if so, what is the x coordinate 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 in the positive direction of the axis, does it reach a turning point (if so, what is the x coordinate of that point) or does it escape from the plotted region (if so, what is its speed at x: J.0 cm)? What are the

(c) Magnitude F and

(d) Direction (positive or negative direction of the x axis) of the electric force on the electron if the electron moves just to the left of x = 4.0 cm? What are?

(e) F and

(f) The direction if it moves just to the right of x = 5.0cm?
