Question

Two protons are a fixed distance 2l from each other. An electron is placed a vertical distance y along the midpoint line.

a) Find the magnitude and direction of the force on the electron as function of l and y (both positive values of y, i.e., both above and below the line).

b) Show that y << l that the force on the electron is proportional to the distance y and the electron will undergo simple harmonic motion.

c)Find the distance l such that the electron will oscillate with a frequency of 7.5x10^14 Hz.
