In the arrangement shown in figure, pulley is smooth and massles and all the strings are light let $F_1$ be the force exerted on the pulley in case $(i)$ and $F_2$ the force in case $(ii)$. Then
$F_1 > F_2$
$F_1 < F_2$
$F_1 = F_2$
$F_1 = 2F_2$
A smooth cylinder of mass $m$ and radius $R$ is resting on two corner edges $A$ and $B$ as shown in fig. The relation between normal reaction at the edges $A$ and $B$ is
