1. Consider a particle of mass m in a one- dimensional box -L< x < +L as shown below.
The potential of the system is given as
0 -L < x < +L
V =
8 x <-L and x > +L
(a) Determine the energy eigenvalue of the particle.
(b) Show that the expectation value of the momentum

= 0.
(c) Determine the expectation value of the kinetic energy .
(d) What is the energy eigen values if the boundary of thebox
is shifted to -L < x < +L/2

A particle of mass m is bound in a finite one-dimensional squarewell described by the potential energy function: V(x)=0 for x<a(region I)
=-v0 for -a<=x<=a (region II) with v0>0
=0 for x>a (region III)
The energy of the particle has some definite negative value-v0<E1<0.
Consider the time independent Schrodinger equation.
Question: In each of the three regions write the normalizablespatial wave function f(x) of the particle assuming that f is aneven function of x, i.e. f(x)=f(-x) and calculate the constants inyour function that are determined by the given quantities.
