If You Have Two Moons That Have the Same Radius

question 17

Multiple Choice

If you have two moons that have the same radius, but Moon A is denser and has 2 times the mass of Moon B, how do their escape velocities compare?

• A) Moon A has an escape velocity that is 1.4 times larger than Moon B.
• B) Moon A has an escape velocity that is 1.4 times smaller than Moon B.
• C) Moon A has an escape velocity that is 2 times smaller than Moon B.
• D) Moon A has an escape velocity that is 2 times larger than Moon B.
• E) Because gravity affects all masses the same, the escape velocities are the same.
