nrmli we would solv such prblem as fsin50 + r =12..but we dont tke R here.???y..????
fsin50 is vvrtical cmponent of f!!!wht about R.?the reaction ov tble.?

Verically Fsin50=Fsin20+12
F(sin50-sin20)=12
F=12/(sin50-sin20)
G=Fcos50+Fcos 20

what reaction force??
12 N is not the weight of the particle, if you mean the normal contact force..?
