Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

time independent schrodinger wave equation for a cubic box comparing it , we get ..... nx= ny=nz = 1 so E= ( nx^2+ny^2+nz^2)h^2/(8ma^2) this is the energy of a particle of cubic box having length a so, E=(1+1+1)h^2/(8ma^2) E= 3h^2/(8ma^2)
