Homework Statement
A proton moves along the x-axis, where an arrangement of source charges has created the electric potential V=6000x^2, where V is in volts and x is in meters.
(a) Graph the potential between x = -5.0 and x = +5.0.
(c) By exploiting the analogy with the potential energy of a mass on a spring, determine the "effective spring constant" of the electric potential.
(d) What is the proton's oscillation frequency (in Hz)?
Homework Equations
U=qV
[tex]U=\frac{1}{2}kx^2[/tex]
The Attempt at a Solution
(a) The potential is just a parabola
(c) [tex]
U=\frac{1}{2}kx^2=qV=6000qx^2[/tex]
[tex]k=2 \times 6000q[/tex]
(d) I can't even grasp what this means. Does the proton oscillate? The voltage only goes to zero once.
