(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

I've attached my past paper question, which contains the relevant integral identity too.

3. The attempt at a solution

This question is relatively simple, yet I can't seem to complete it.

I used the schrodinger equation which is:

-(ħ²/2m)[tex]\nabla^2[/tex]u + Vu = Eu

I then used the identity given in the question, to differentiate the wavefunction w.r.t to r twice. (In this part I had to differentiate by products since there was another factor of r).

Differentiating the wavefunction twice gave me:

(Z²/a²).r.u

When I put this into the schrodinger equation above, knowing V and E, I dont get the correct answer.
