Question

calculate the work done in lifting a 200kg of water through a vertical distance of 6m. Assume g=10m/s2​

Answer 1

Work done = Potential Energy

Work done = mgh

Work done = 200 × 6 × 10

Work done = 12000 Joules

Answer 2

$\huge{\underline{\underline{\sf{\green{SOLUTION:-}}}}}$

⠀

$\sf{\underline{\red{Answer-}}}$

⠀

• The work done is 12000 Joules.

⠀

$\sf{\underline{\red{Given-}}}$

⠀

• The work done in lifting a 200kg of water through a vertical distance of 6m. (Assume g = 10m/s²).

⠀

$\sf{\underline{\red{Calculate-}}}$

⠀

• We have to calculate the work done.

⠀

$\sf{\underline{\red{Explanation-}}}$

⠀

$\sf{\underline\blue{Formula\:Used\:Here-}}$

⠀⠀

$\bigstar\boxed{\sf{\pink{W=m \times g \times h}}}$

⠀

$\sf \: Here:-$

⠀

$\longrightarrow\sf \: Mass \: of \: water, \: m=200kg$

⠀

$\longrightarrow\sf \: Acceleration \: due \: to \: gravity, \: g=10 \: m/ {s}^{2}$

⠀

$\longrightarrow\sf \: Height, \: h=6m$

⠀

$\sf{\underline{\red{Now\:Putting\:the\:values:-}}}$

⠀

$\longrightarrow\sf \: W=200 \times 10 \times 6$

⠀

$\longrightarrow\sf \: W=12000 \: Joules$

⠀

• Thus, the work done is 12000 Joules.
