Answer 2

$\begin{gathered}\underline{\underline{\sf{ \color{purple}{\qquad To \: Find\:: \qquad} }}}\\\\\end{gathered}$

• Potential energy

$\begin{gathered}\underline{\underline{\sf{ \color{purple}{\qquad Solution\:: \qquad} }}}\\\\\end{gathered}$

Given that,

• Weight = 100 N

• Height = 10 m

$\begin{gathered}\dag\;{\underline{\frak{As\;we\;know\;that,}}}\\ \\\end{gathered}$

$\begin{gathered}\star\;{\boxed{\sf{\purple{Weight= Mass \times Acceleration }}}}\\ \\\end{gathered}$

$\begin{gathered}\qquad \quad {:} \implies \sf \: {100 = Mass \times 10 } \\\end{gathered}$

$\begin{gathered}\qquad \quad {:} \implies \sf \: { \dfrac{100}{10} = Mass } \\\end{gathered}$

$\begin{gathered}\qquad \quad {:} \implies \sf \: { Mass = \cancel\dfrac{100}{10} } \\\end{gathered}$

$\begin{gathered}\qquad \quad {:} \implies \sf{ Mass = 10 \: kg } \\\\\\\end{gathered}$

$\begin{gathered}\dag\;{\underline{\frak{Again}}}\\ \\\end{gathered}$

$\begin{gathered}\star\;{\boxed{\sf{\purple{Potential ~ energy= Mass \times Acceleration \times Hight }}}}\\ \\\end{gathered}$

$\begin{gathered}\qquad \quad {:} \implies \sf \: {Potential \: energy = 10 \times 10 \times 10 } \\\end{gathered}$

$\begin{gathered}\qquad \quad {:} \implies \sf{ Potential \: energy = 1000 \: J } \\\\\\\end{gathered}$

$\begin{gathered}\sf \: ∴ \: Hence, \: the \: potential \: energy \: is \: 1000 J \\\\\end{gathered}$
