Question

Problem 2.2 Show that E must exceed the minimum value of V (x), for every
normalizable solution to the time-independent Schrödinger equation. What is the
classical analog to this statement? Hint: Rewrite Equation 2.5 in the form
d²
2m
[V(x) - E];
dx²
if E < Vmin, then and its second derivative always have the same sign-argue
that such a function cannot be normalized.
h² d²
2m dx²
+ Vy = Ev.

In this question we will consider a finite potential well in which V = −V0 in the interval −L/2 ≤ x ≤ L/2, and V = 0 everywhere else (where V0 is a positive real number). For a particle with in the range −V0 < E < 0, write and solve the time-independent Schrodinger equation in the classically allowed and classically forbidden regions. Remember to keep the wavenumbers and exponential factors in your solutions real!
Problem 4.25 If electron, radius [4.138] 4πεmc2 What would be the velocity of a point on the "equator" in m /s if it were a classical solid sphere with a given angular momentum of (1/2) h? (The classical electron radius, re, is obtained by assuming that the mass of the electron can be attributed to the energy stored in its electric field with the help of Einstein's formula E = mc2). Does this model make sense? (In fact, the experimentally determined radius of the electron is much smaller than re, making this problem worse).
