Question

Why is the force of gravity greater for an object orbiting Earth than for the

same object orbiting Pluto?
A. Earth has only one moon, while Pluto has three.
B. Earth is closer to the sun than Pluto.
C. Earth has a heavy atmosphere and Pluto does not.
D. Earth is more massive than Pluto.

Answer 1

d) Earth is more massive than Pluto.

Step-by-step explanation:

The force of gravity is greater for an object orbiting the Earth than for the same object orbiting Pluto, because Earth is more massive than Pluto.

The common factor is that the greater the planet's mass, the greater its gravitational force acting on an object. Hence, the option (d) is the correct answer.
