The work done by an external force to move a charge from point A to point B
is 15x10 44). If the charge was started
from rest and had of kinetic energy
4.82x10 KJ when it reached point B.
what must be the potential difference
between A and B? How far apart is
point B from point A?

An electron is trapped at a defect in a crystal. the defect may be modeled as a one-dimensional, rigid-walled box of width 1.00 nm. (a) sketch the wavefunctions and probability densities for the n 1 and n 2 states. (b) for the n 1 state, nd the probability of nding the electron between x1 0.15 nm and x2 0.35 nm, where x 0 is the left side of the box. (c) repeat (b) for the n 2 state. (d) calculate the energies in electron volts of the n 1 and n 2 states
