British list me pls

Answer 2

$\huge \fbox{Answer}$

$\large \underline{\underline{ \frak{ \color{red}Given:}}}$

$\sf \mapsto{Mass \: of \: body \: on \: moon=40kg}$

$\large \underline{\underline{ \frak{ \color{re}To \: find:}}}$

$\sf{ \leadsto{Weight \: of \: body \: on \: earth. }}$

$\large \underline{\underline{ \frak{ \color{blue}Formula \: required:}}}$

$\dag { \boxed{ \rm{Weight_{(on \: earth)}=mass_{(body)}×gravity_{(acceleration)}}}}$

$\large \underline{\underline{ \frak{ \color{indigo}Concept \: used:}}}$

${ \rightarrow \sf{Mass_{(body)} \: is \: always \: equal \: anywhere \: in \: universe.}}$

${ \rightarrow{ \sf{Acceleration \: due \: to \: gravity \: is \: 10m {s}^{ - 2}. }}}$

$\rightarrow \sf{1N=1kg×10m {s}^{ - 2} }$

$\large \underline{ \underline{ \frak{ \pink{According \: to \: Question:}}}}$

${:: \implies{ \sf{Weight_{(on \: earth)}=mass_{(body)}×gravity_{(acceleration)}}}}$

${:: \implies{ \sf{Weight_{(on \: earth)}=40kg×10m {s}^{ - 2} }}}$

${:: \implies{ \sf{Weight_{(on \: earth)}=400N}}}$

$\bf \underline{Hence,}$

$\: \: \: \: \: \: \: \: \: \: \: \: \star{ \boxed{ \rm{Weight_{(on \: earth)}=400N}}}$
