Question

The mass of the body on moon is 40kg, what is the weight on the earth? (g=9.8m/sec²)​

Answer 1

Answer:

Mass will be same on earth as on moon bcoz mass is constant .

so, W = mg where

W=weight, m=mass and g=gravitational force

W=40×9.8

=392N

Weight on the earth is 392 (N) Newton.

Answer 2

$\; \star \; {\underline{\boxed{\pmb{\orange{\frak{ \; Given\; :- }}}}}}$

➺ Mass of a body is 40 kg.

$\star \;{\underline{\boxed{\pmb{\red{\frak{ \; To \; Find \; :- }}}}}}$

➺ Weight = ?

$\; \star \; {\underline{\boxed{\pmb{\purple{\frak{ \; SolutioN \; :- }}}}}}$

$❒{\underline{\underline{\sf{ \; Calculating \: weight \;  \: : - }}}}$

${\underline{\underline{\sf{ \; Formula \; Used \; :- }}}}$

${ \underline{ \boxed{\sf{Weight =Mass×Gravitational \:Acceleration }}}}$

${\longrightarrow \; {\sf{Weight=Mass×Gravitational Acceleration }}} \;$

${\longrightarrow \; {\sf{Weight = 40 \times 9.8 }}} \;$

${\longrightarrow \;{\sf{Weight = 40 \times \dfrac{98}{10} }}} \;$

${\longrightarrow \;{\sf{Weight=4\cancel0\times \dfrac{98}{ \cancel{10}} }}} \;$

${\longrightarrow \; {\sf{Weight = 4 \times 98}}} \;$

${\; \longrightarrow \; {{ \pink{ \underline{ \boxed{ \frak{ Weight=392N}}}}}} }\;\red\bigstar$

$\begin{gathered} \\ \\ \end{gathered}$

$\therefore$Weight of the body is 392 N

$\begin{gathered}\begin{gathered}\begin{gathered} \\ {\underline{\rule{300pt}{9pt}}} \end{gathered} \end{gathered}\end{gathered}$
