Which is greater, the gravitational attraction between a newborn baby and the Earth, or the gravitational attraction between the Earth and all the planets of the solar system?
A)The attraction between the baby and Earth
B)The attraction between the planets and Earth
C)They are roughly equal
D)The baby's and the planets gravitational attractions are inversely proportional to each other

Question

Quizplus · Accepted Answer

The gravitational force between two objects is given by the formula F= G * (m1*m2)/r^2, where G is the gravitational constant, m1 and m2 are the masses of the two objects, and r is the distance between them. The mass of a newborn baby is much smaller than the mass of any planet in the solar system, and the distance between the baby and the Earth is much smaller than the distance between the Earth and any planet in the solar system. Therefore, the gravitational attraction between the baby and Earth is much greater than the gravitational attraction between Earth and all the planets of the solar system combined.
