Use the table of the masses of several objects to answer the question.
Object. Mass (grams)
Paper clip 1.0
Penny 2.5
Book 860
Cereal box 500
Small pot 1,200
Between which two objects is gravitational attraction the greatest of placed 1 meter apart
A. Between the penny and the small pot.
B. Between the book and the cereal box
C. Between the small pot and the book
D. Between the paper clip and the penny
To determine which two objects have the greatest gravitational attraction, we need to calculate the gravitational force using the formula:
Force = (G * mass1 * mass2) / distance^2
Where G is the gravitational constant (approximately 6.67 x 10^-11 Nm^2/kg^2).
Let's calculate the forces for each pair of objects:
1. Between the penny and the small pot:
Force = (6.67 x 10^-11 * 2.5 * 1200) / 1^2 = 2.004 x 10^-7 N
2. Between the book and the cereal box:
Force = (6.67 x 10^-11 * 860 * 500) / 1^2 = 2.295 x 10^-6 N
3. Between the small pot and the book:
Force = (6.67 x 10^-11 * 1200 * 860) / 1^2 = 7.1208 x 10^-7 N
4. Between the paper clip and the penny:
Force = (6.67 x 10^-11 * 1.0 * 2.5) / 1^2 = 1.6685 x 10^-9 N
Comparing the forces, we can see that the gravitational attraction is highest between the book and the cereal box (2.295 x 10^-6 N). Therefore, the answer is B. Between the book and the cereal box.
....but the small pot is more massive than the cereal box.
Pick the two most massive.
