Question

the body of mass 500g
is kept at the height 20meter what is the energy of it

Answer 1

Answer:

given

height,h=20

mass,m=500

gravity,g=10

energy=mgh

=500*10*20

=1,00,000

Answer 2

$\huge\bf{ \underline{Question}}$

• A body of mass 500g is kept at the height of 20m what is the energy of it ?

$\huge\bf{ \underline{Answer}}$

• 98000 Joule

$\huge\bf{ \underline{Formula\:Used}}$

$\bf{ \red{ \underline{ \boxed{P.E\:=\:mgh}}}}$

$\huge\bf{ \underline{Solution}}$

$\sf{⟹P.E\:=\:mgh}$

$\bf{Put\:value\:of\:g\:=\:9.8m/\ s^{2}}$

$\sf{⟹P.E\:=\:500\times9.8\times20}$

${}$

$\sf{⟹P.E\:=\:500\times\dfrac{98}{10}\times20}$

${}$

$\sf{⟹P.E\:=\:500\times\dfrac{98}{1\cancel{0}}\times2\cancel{0}}$

${}$

$\sf{⟹P.E\:=\:98000\:Joule}$

➠ Potential Energy is energy due to position of a body

➠ P.E = mgh

➠ Value of g = 9.8 $\sf{m/\ s^{2}}$

➠ Kinetic Energy is energy due to motion of a body.
