Question

An object of mass 40 kg is placed at a height of 15 m above earth's surface, how much potential energy does it possess. take g =10 m/s^2​

Answer 1

Answer:

$\large\tt\color{cyan}\underline{\underline{Question:}}$

$\textsf{An object of mass 40 kg is placed at a height}$

$\textsf{of 15 m above the earth's surface , how much}$

$\textsf{potencial energy does it possess.}$

$\textsf{Take g=10 m/s²}$

$\large\tt\color{orange}\underline{\underline{Given:}}$

$\textsf{Mass of the object = 40 kg}$

$\textsf{Height where the object placed = 15 m}$

$\textsf{Graveity due to acceleration = 10 m/s²}$

$\large\tt\color{blue}\underline{\underline{To\:find:}}$

$\textsf{How much potential energy does it possess}$

$\large\tt\color{red}\underline{\underline{We\:know}}$

$\boxed{P.E=mgh}$

$\textsf{P.E=Potential energy}$

$\textsf{m=Mass}$

$\textsf{g=Gravity due to acceleration}$

$\textsf{h=Height}$

$\large\tt\color{green}\underline{\underline{Concept:}}$

$\textsf{Multiply the m with g with h .}$

$\textsf{And the answer which will come that will be}$

$\textsf{the answer.}$

$\large\tt\color{magenta}\underline{\underline{Solution:}}$

$\bold{Taken , P.E=mgh}$

$\Rightarrow\bold{P.E=m×g×h}$

$\Rightarrow\bold{P.E=40kg×10m/s²×15m}$

$\Rightarrow\bold{P.E=400×15m}$

$\therefore\boxed{\underline{\purple{P.E=6000N}}}$

_________________________________________

So , the potential energy possess by the object is 6000 N.
