REASONING
The weight of a person on the earth is the gravitational force
F
earth
that it exerts on the person. The magnitude of this force is given by Equation 4.3 as
earth
person
earth
2
earth
mm
FG
r
=
where
r
earth
is the distance from the center of the earth to the person. In a similar
fashion, the weight of the person on another planet is
planet
person
planet
2
planet
r
=
We will use these two expressions to obtain the weight of the traveler on the planet.
SOLUTION
Dividing
F
planet
by
F
earth
we have
planet
person
2
2
planet
planet
planet
