i am getting same expressions except for that of α

for α i am gtting following range

tan^{-1}\frac{1-\mu }{1+\mu }\leq \alpha \leq tan^{-1}\frac{1+\mu }{1-\mu }

@Jai Hind,
Your answers for f and N are correct. But the values of α you have got is incorrect.

@subho, that's correct.

taking out the angles is very easay

1st case mgsin@-mgcos@=un this time uN is in the upward direction
and N=mgcos@+mgsin@
and in 2nd case mgcos@-mgsin@=uN here uN is in downward direction
simple as tht
