Question

25. Which units would be the most appropriate to use to measure the degree of attraction between two objects due to their mass?

Answer 1

The attraction between two objects is force.
As such, if you don't describe the degree of attraction
in units of force, you're doomed.

Whether to use micronewtons, millinewtons, newtons,
giganewtons, ounces, pounds, or tons, really depends on
the size of the force, which in turn depends on the masses
of the two objects and the distance between them.  You'll
want to select the unit that produces the most convenient
number.  And of course, you'll want to favor the SI units.

Answer 2

The correct answer to the question is : Newton ( N )

EXPLANATION:

Before going to answer this question, first we have to understand the gravitational force.

Gravitational force is the mutual force of attraction between two bodies with which every body in the universe is attracted with every other body.

The gravitational force between two bodies having masses M and M' separated by a distance R is calculated as-

              Gravitational force F = $G\frac{MM'}{R^2}$

Here, G is known as the universal gravitational force constant.

Hence, gravitational force is a force.

We know that unit of force is newton ( N ).

Hence, the degree of attraction between two objects is measured in newton units.
