please follow me because i am new

Answer 2

$\Huge \mid\underline{\overline{\fbox{Answer}}} \mid$

$\Large \underline{\underline{\red{\frak{Given:}}}}$

$\sf \rightarrow{Mass \: of \: bag \: of \: rice=50kg}$

$\sf \rightarrow{Potential \: energy\:required \: on \: bag=5000J}$

$\Large \underline{\underline{\red{\frak{To \: find:}}}}$

$\sf \leadsto{Height \: of \: bag \: which \: should \: be \:required\:to\: raised\:in\:energy. }$

$\Large \underline{\underline{\red{\frak{Formula \: required:}}}}$

$\star {\fbox{ \blue{ \bf{Potential \: energy\:required \: on \: bag=mass(m)×gravity(g)×height(h)}}} }\star$

$\Large \underline{\underline{\red{\frak{Concept \: required:}}}}$

$\mapsto \sf{Gravity(g)\: required \: on \: bag \: is \: 10m {s}^{ - 1}. }$

$\Large \underline{\underline{\red{\frak{According \: to \: Question:}}}}$

${{\implies{ \bf{Potential \: energy\:required \: on \: bag=mass(m)×gravity(g)×height(h)}}} }$

${{\implies{ \sf{5000J=50Kg \times 10m{s}^{ - 1} ×height(h)}}} }$

$\sf {\implies {height(h) = { \xcancel{ \frac{5000}{50 \times 10} } = 10m}}}$

$\fbox{The \: height \: of \: bag \: to \: raised \: in \: energy \: is \: 10m.}$
