What will be the weight of a person on earth, who weighs 12 N on the moon?

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

$\underline{\underline{\mathfrak \red{Remember-}}}$

Acceleration due to gravity on moon is ${\sf \dfrac{1}{6}}$ of acceleration due of gravity of Earth.

⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯

Let ,

Acceleration due to gravity on moon is g'

Acceleration due to gravity on Earth is g

$\large{\sf g'=\dfrac{1}{6}g }$

Person weight on moon is 12 N

•°• Person weight on Earth will be ⎯

$\implies{\sf g = 12×6 }$

$\implies{\bf \red{g=72\:N}}$

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

Option (b) 72 N

Weight of person on Earth is ${\bf \red{72\:N}}$
