The image shows a model of the gravitational field around Earth. An illustration of the earth with concentric circles going out away from the earth and radial lines going out away from the earth. On each radial line is an arrow pointing toward earth.
Which best describes the model?

The field exerts an attractive force only outside of the ring of arrows that point toward Earth’s surface.
The field exerts an attractive force only within the ring of arrows that point toward Earth’s surface.
The strength of the field increases as you get farther from Earth, as shown by the larger spaces between the circles.
The strength of the field increases as you get closer to Earth, as shown by the smaller spaces between the circles.
