Variation of G Due to the Rotation of Earth

If accelerati...

Question

If acceleration due to gravity is $10 m s^{- 2}$ , what is the potential energy of a body of mass $1 k g$ kept at a height of $5 m$ ?

Open in App

Solution

Potential energy $= m \times g \times h$ (here $m = 1 k g$ , $g = 10 m s^{- 2}$ , $h = 5 m$ )
Potential energy $= 1 k g \times 10 m s^{- 2} \times 5 m$
Potential energy $= 50 J$
