30agree with qwerty!
agreed with the equations, except one , that is N = 2
they have given that force applied by stick on the ring is 2 N, that means
( N2 + (μN)2 )1/2 = 2
but with this i didnt get an integral answer. so i tried with N =2 , and got ans 4 . But that isnt correct.
Or am i making a mistake somewhere? [7]

23i kindly request experts like kaymant sir and nishant sir and all others to please comment on this question ....
49yaar I think the question gives N=2
what is there not to agree??
23force exerted by stick on ring will be Normal force vector + friction vector ,
not merely normal force
49maine pura galat kiya is question ko! :P
I thot that the boy was pushing downwards! ;) :P
hehe!
Anyway now the question seems the boy is trying to push the ball horizontally with force 2 N.
Hence, N=2N
23subhomoy , if N2 +μ2N2=22 would of given an integral ans between 0 to 9 , then what would be your opinion ?
