1.

Jupiter has a mass approximately 300 times greater than Earth’s and a radius about 11 times greater. How will the gravitational acceleration at the surface of Jupiter compare to that at the surface of the Earth?

- Greater
- Less
- About the same
- Not enough information

**2**.

Given Newton’s universal law of gravitation (Equation 6.40), under what circumstances is the force due to gravity maximized?3.

In the formula g=GMr2g=GMr2, what does *G* represent?

- The acceleration due to gravity
- A gravitational constant that is the same everywhere in the universe
- A gravitational constant that is inversely proportional to the radius
- The factor by which you multiply the inertial mass to obtain the gravitational mass

**4**.

Saturn’s moon Titan has a radius of 2.58 × 10^{6} m and a measured gravitational field of 1.35 m/s^{2}. What is its mass?5.

A recently discovered planet has a mass twice as great as Earth’s and a radius twice as large as Earth’s. What will be the approximate size of its gravitational field?

- 19 m/s
^{2} - 4.9 m/s
^{2} - 2.5 m/s
^{2} - 9.8 m/s
^{2}

**6**.

4. Earth is 1.5 × 10^{11} m from the Sun. Mercury is 5.7 × 10^{10} m from the Sun. How does the gravitational field of the Sun on Mercury (*g _{SM}*) compare to the gravitational field of the Sun on Earth (
