Question
.55 The radial probability density for the ground state of the
hydrogen atom is a maximum whenr = a, where a is the Bohr ra-
dius. Show that the average value of r, defined as
P(r) r dr,
has the value 1.5a. In this expression for ravgs each value of P(r) is
weighted with the value of r at which it occurs. Note that the average
value of r is greater than the value of r for which P(r) is a maximum.
