Planet a Has Twice the Mass of Planet B

question 79

Multiple Choice

Planet A has twice the mass of Planet B. From this information, what can we conclude about the acceleration due to gravity at the surface of Planet A compared to that at the surface of Planet B?

• A) The acceleration due to gravity on Planet A is greater than the acceleration due to gravity on Planet B, but we cannot say how much greater.
• B) The acceleration due to gravity on Planet A must be four times as great as the acceleration due to gravity on Planet B.
• C) The acceleration due to gravity on Planet A is the same as the acceleration due to gravity on Planet B.
• D) The acceleration due to gravity on Planet A must be twice as great as the acceleration due to gravity on Planet B.
• E) We cannot conclude anything about the acceleration due to gravity on Planet A without knowing the radii of the two planets.
