Question

An object's weight is dependent upon its location in the universe. Why is this true?

Answer 1

Explanation :

We know that the weight of an object is given by :

$W=mg$

Where,

m is the mass

g is the acceleration due to gravity.

The value of g changes from one location to another.

An object's weight is dependent upon its location in the universe. This statement is true. This is because g varies in different places so the weight also varies.

Hence, the correct option is (D) " This is true because weight is the magnitude of gravitational force acting on an object, and since gravitational force varies in different places in the universe, weight also varies ".

Answer 2

Because an object's weight is the measure of the gravitational
forces between the object and other things that have mass. 

In its travels around the universe, the object can be in the
neighborhood of other things with huge mass or tiny mass,
and it can be nearer to them or farther away from them.  So
the gravitational forces between the object and other things
can have widely different values in different places.

Read the choices very carefully. 
I think 'D' is the one that says this.
