1taking 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
Is
N= mg(cos α+sinα )
f= mg(cosα-sinα)
\alpha \leq \frac{\mu -1}{\mu +1}
-
UP 0 DOWN 0 2 5

62are these only for Anant sir?
(What if others want to solve? [3] :P)
49i 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 }
66@Jai Hind,
Your answers for f and N are correct. But the values of α you have got is incorrect.
@subho, that's correct.
