Answer 1

Answer:

ANSWER :-

$\sf \: We \: know \: the \: formula \: of \: presure$

$➢\sf \: presure = \frac{force}{area}$

$\sf \: As \: \: the \: \: given \: \: relation \: \: we \: got \: that -$

$\sf \: presure \: is \: inversaly \: propotional \: to \: \bold{area}$

$\sf \: Hence \: we \: should \: take \: the \: side \: where \\ \sf area \: is \: minimum \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:$

$\sf \: So \: \: body \: \: should \: \: be \: \: placed \: \: as \: \: shown \: \: \\ \sf \: in \: \: fig. \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:$
