Hi, I have to derive the ket |\phi> that corresponds to the wavefunction \phi(x). I've done this out with the information given to point where I've gotten: |\phi> = \alpha|0> + \beta|2> How can I go further in evaluating this?

Homework Statement Find the absolute error for the following function: f = (xy/z)+5w Homework Equations Equation for an error vector: df = (df/dw)dw + (df/dx)dx + (df/dy)dy + (df/dz)dz Equation for the absolute error: (df)^2 = (df/dw)^2(dw)^2 + (df/dx)^2(dx)^2 +...

I've tried that, but it gives me an answer of 2.16*10^4 N/C , instead of the answer of 1.53*10^4 N/C, and I can't figure out why.

A +12 nC charge is located at the origin. What are the electric fields at the positions (x,y) = (5.0 cm, 0 cm), (-5.0 cm, 5.0 cm), (-5.0 cm, -5.0 cm)? Write each electric field vector in component form. I got the answer for the first one, but I can't figure out how to get the answers for the...

Okay, thank you.

Okay, but how do you find the electric potential due to the two protons?

1. The hydrogen molecular ion, with one electron and two protons, is the simplest molecule. The equilibrium spacing between the protons is 0.11 nm. Suppose the electron is at the midpoint between the protons and moving at 1.5*10^6 m/s perpendicular to a line between the protons. How far (in nm)...
