Gravitational force increases as the distance between objects increases.
Gravitational force increases as mass of objects decreases.
Gravitational force increases as the mass of objects increases.

The statement "Gravitational force increases as the mass of objects increases" is true.
The statement that is true about the geocentric model is that it shows Earth at the center of the solar system.
The statement that is true about the geocentric model is that it shows Earth at the center of the solar system.
To determine the correct answer, we can break down the question and analyze each statement.
1. "It shows the orbits of the planets as elliptical." - This statement is not true for the geocentric model. The geocentric model, developed by ancient astronomers, did not account for elliptical orbits of planets. Instead, it assumed that planets moved in perfect circles around the Earth.
2. "It shows Earth at the center of the solar system." - This statement is true. The geocentric model places the Earth at the center of the universe, with all celestial bodies, including the Sun and other planets, revolving around it.
3. "It shows the Sun at the center of the solar system." - This statement is not true for the geocentric model. It is actually the opposite of the geocentric model. The Sun being at the center is the concept known as the heliocentric model, which was proposed by Nicolaus Copernicus and later confirmed by observations made by astronomers like Galileo Galilei.
Therefore, the correct statement about the geocentric model is that it shows Earth at the center of the solar system.
