A sphere is rotating between two rough inclined walls as shoen in fiogure. Cofficent of friction between each wall and the sphere is `(1)/(3)`. If `f_(1)` and `f_(2)` be the ffriction forces at PO and Q. Then `(f_(1))/(f_(2))` is
A. `(4)/(sqrt3)+1`
B. `(1)/(sqrt3)+2`
C. `(1)/(2)+sqrt3`
D. `1+2sqrt3`
