A sphere is placed rotating with its centre initially at rest in a corner as shown in Figs. (a) and (b). Coefficient of friction
\( \mathrm{P} \) between all surfaces and the sphere is \( 1 / 3 \). Find the ratio of

W the friction forces \( f_{a} / f_{b} \) by ground in situations (a) and (b).
(a)
(b)
(1) 1
(2) \( \frac{9}{10} \)
(3) \( \frac{10}{9} \)
(4) None of these
