shell of same mass. Shell is free to move on the
smooth ground. If particle is given a gentle push
and reaches to angular position q as shown in fig.
ure then for an observer fixed on a shell
, ratio of re-
action force exerted by shell to pseudo force (as
observed from shell) acting on particle, is



(1) sin theta
(3) cos theta
(2) cosec theta
(4) sec theta​
