# Physics' concept - 5

A person attaches an electronic weighing machine on his feet and jumps from a high mountain on earth (I don't know why) .While falling , he sees that his weighing machine reads his weight as '$a$' kilograms. The same person (alive, I don't know how) then performs the same experiment on the moon and while falling his weighing machine reads his weight as '$b$' kilograms.

Find the value of $\dfrac{a}{b}$.
