    Solving for Virial Theorem (look at image attached for better symbol representation)

    a. In a one-dimensional problem, consider a particle with the Hamiltonian:
    H = p^2/2m + V(X)
    where: V(C) = lambaX^n

    Calculate the commutator [H, XP]. If there exists one or several stationary states |> in the potential V, show that the mean values <T> and <V> of the kinetic and potential energies in these states satisfy the relation: 2<T> = n<V>
