(a)
Show that
(a)
Answer to Problem 5.1P
It is proved that
Explanation of Solution
Given, the separation between the two particles is
The position of the center of the mass is
The reduced mass of the system is
Substitute equation (I) in (II) and solve for
Hence it is proved that
Similarly substitute equation (I) in (II) and solve for
Hence it is prove that
Let the coordinates of
Equation (I) and (II) with respect to
Substitute
Similarly equation (I) and (II) with respect to
Similarly equation (I) and (II) with respect to
Adding,
Hence it is proved that
Similarly for particle
Equation (I) and (II) with respect to
Substitute
Similarly equation (I) and (II) with respect to
Similarly equation (I) and (II) with respect to
Adding,
Hence it is proved that
Conclusion:
Thus, it is proved that
(b)
Show that the Schrodinger equation becomes
(b)
Answer to Problem 5.1P
It is proved that the Schrodinger equation becomes
Explanation of Solution
