Proton in a well. Figure 24-51 shows electric potential V along an x axis.A proton is to be released at x = 3.6 cm with initial kinetic energy 4.0 eV. The scale of the vertical axis isset by Vs = 10.0V.
(a) If it is initially moving in thenegative direction of the axis, it either reaches a turning point(if so, what is the xcoordinate of that point) or itescapes from the plotted region (if so, what is its speedat x = 0)?
(b) If itis initially moving in the positive direction of the axis, iteither reaches a turning point (if so, what isthe x coordinate of that point) or it escapesfrom the plotted region (if so, what is its speedat x = 6.0 cm)?
(c) What is the electric force (including sign) on the proton if the proton moves just to the left of x = 3.0cm?
(d) What is the electric force(including sign) on the proton if the proton moves just to theright of x = 5.0 cm?
