How much height must be lifted an object of mass 10kg to have P.E. 2000J [g=10m/s2]

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

$\large\underline{\underline{\sf Given:}}$

• Mass of object ( m ) = 10 kg
• Potential Energy ( U ) = 2000 J
• g = 10 m/s²

$\large\underline{\underline{\sf To\:Find:}}$

• Height ( h )

✪$\large{\boxed{\bf \blue{U = mgh }}}$

$\implies{\sf 2000=10×10×h}$

$\implies{\sf h = \dfrac{2000}{100} }$

$\implies{\bf \red{h = 20\:m}}$

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

Height at which object is lifted is ${\bf \red{20\:m}}$
