Hi,
when force f is not acting
normal by wedge on ball , N1 = mg cos Ø .....................(1)
when f is applied,
total acceleration of wedge & ball, a = F/ (M+m)
we have to make the fbd of ball with respect to the vedge
in this there will be three forces mg, N & ma ( becoz we are seeing w.r.t. wedge )
ball is at rest with respect to wedge,
so, horizontal forces, N2 sinØ = ma
N2 = ma / sinØ
N2 = mF/(M+m) sinØ............(2)
(2)/ (1) .....
N2 /N1 = F/(M+m)g sin Ø cos Ø
