Homework Statement


Problem 8.
1. Express the distance x_c as a function of the mass m and the restoring
parameter c used in Problem 7.

(Problem 7.
1. Calculate the energy of a particle subject to the potential V(x) = V_0 +<br /> cx^2/2 if the particle is in the third excited state.
2. Calculate the energy eigenvalues for a particle moving in the potential
V(x) = cx^2/2 + bx.)

Homework Equations



H=\frac{p^2}{2m}+\frac{m\omega ^2}{2}x^2


The Attempt at a Solution


I cannot understand what is actually meant by this parameter x_c and how to approach the problem.

It might help if you provided the complete problem statement for problem 8. The reference to problem 7 just means c is a spring constant; it doesn't say anything about what xc is supposed to represent.
 
Problem 8.
1. Express the distance x_c as a function of the mass m and the restoring
parameter c used in Problem 7.
2. If c is multiplied by 9, what is the separation between consecutive eigenvalues?
3. Show that x_c is the maximum displacement of a classical particle moving
in a harmonic oscillator potential with an energy of \hbar\omega/2.
 
Well, your confusion is understandable if this is all the info you have. I have no idea how xc is defined either.
 
Hello everyone, I’m considering a point charge q that oscillates harmonically about the origin along the z-axis, e.g. $$z_{q}(t)= A\sin(wt)$$ In a strongly simplified / quasi-instantaneous approximation I ignore retardation and take the electric field at the position ##r=(x,y,z)## simply to be the “Coulomb field at the charge’s instantaneous position”: $$E(r,t)=\frac{q}{4\pi\varepsilon_{0}}\frac{r-r_{q}(t)}{||r-r_{q}(t)||^{3}}$$ with $$r_{q}(t)=(0,0,z_{q}(t))$$ (I’m aware this isn’t...
Hi, I had an exam and I completely messed up a problem. Especially one part which was necessary for the rest of the problem. Basically, I have a wormhole metric: $$(ds)^2 = -(dt)^2 + (dr)^2 + (r^2 + b^2)( (d\theta)^2 + sin^2 \theta (d\phi)^2 )$$ Where ##b=1## with an orbit only in the equatorial plane. We also know from the question that the orbit must satisfy this relationship: $$\varepsilon = \frac{1}{2} (\frac{dr}{d\tau})^2 + V_{eff}(r)$$ Ultimately, I was tasked to find the initial...
