$\small \underline \bold{For \: an \: object}$:-

$\large \underline \bold{Given}$:-

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \:$mass$\:$=$\:$10 kg

$\: \: \: \: \: \: \: \: \: \: \: \: \:$ height$\:$=$\:$2 m

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:$g$\:$=$\:$10 m/s²

$\large \underline \bold{To \: Find}$:-

The energy possessed by the

$\: \: \:$ object ?

$\large \underline \bold{Usable \: Formula}$:-

$\: \: \: \: \: \: \: \: \: \: \: \: \:$$\large\boxed{\sf\pink{U \: = \: mgh}}$

$\: \: \: \: \: \:$U$\:$=$\:$possessing energy

$\: \: \: \: \: \:$m$\:$=$\:$mass of object

$\: \: \: \: \: \: \:$h$\:$=$\:$height

$\: \: \: \: \: \: \:$g$\:$=$\:$gravi. acceleration

$\large \underline \bold{Solution}$:-

On putting the values in above

$\: \: \: \:$formula -

$\: \: \: \: \: \: \: \: \: \: \:$U$\:$=$\:$10 × 10 × 2

$\: \: \: \: \: \: \: \: \: \: \:$U$\:$=$\:$10² × 2

$\: \: \: \: \: \: \: \: \: \: \:$U$\:$=$\:$100 × 2

$\: \: \: \: \: \: \:$$\large\boxed{\sf\red{U \: = \: 200 \: J}}$

200 joule energy possessed by the

$\: \: \: \: \:$ object.

Answer 2

mass=10 kg

height=2 m

g=10 m/s²

to find:- The energy possessed by the  object ?

usable formula:- U=mgh

U=possessing energy

m=mass of object

h=height

g=gravi. acceleration

solution:-

On putting the values in above formula -

U=10 × 10 × 2

U=10² × 2

U=100 × 2

U=200 J

200 joule energy possessed by the  object.
