The electric field between two parallel plates has a magnitude of 180 N/C. The two plates are 2.5 cm apart.
Recall that the magnitude of the charge on an electron is
1.602 x 10-19 C.
How much work is done to move an electron from the
positive plate to the negative plate?

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
