Final answer:
The magnitude of the gravitational force (F) between Object 1 and Object 2 is given by F = G * (m₁ * m₂) / r². The force on the baby due to Jupiter at its closest distance is approximately 8.44 × 10¹⁸ N. The ratio of the force of the father on the baby to the force of Jupiter on the baby is approximately 2.96 × 10¹³.
Step-by-step explanation:
In physics, the gravitational force (F) between two objects is given by Newton's law of gravitation:
where
is the gravitational constant

are the masses of the objects, and \(r\) is the separation between their centers.
For part (a), the expression for the gravitational force between Object 1 and Object 2 is derived from this formula:
.
For part (b), the force on the baby due to Jupiter is calculated using the same gravitational force formula, with
as the mass of the baby,
as the mass of Jupiter
, and
as the closest distance between Earth and Jupiter
.
For part (c), the ratio of forces is found by dividing the force of the father on the baby by the force of Jupiter on the baby.
