+Standard formula used
+ E = (n^2 * h^2) / (8 * m * L^2))
+ p_n = n*h/(2*pi)

+ Energy levels of electron
+ For (n=1) is 6.019835e-20 J.
+ For (n=2) is 2.407934e-19 J.
+ For (n=3) is 5.417852e-19 J.
+ Energy levels of marble
+ For (n=1) is 1.369512e-63 J.
+ For (n=2) is 5.478050e-63 J.
+ For (n=3) is 1.232561e-62 J.
+ It is clear that the levels in case of marble are very small and are nearly zero. So it is not possible to measure them experimentally.
