Final answer:
The gravitational force between two objects can be calculated using Newton's universal law of gravitation, which depends on the masses of the objects and the distance between their centers.
Step-by-step explanation:
The gravitational force between two objects can be calculated using Newton's universal law of gravitation, which states that the force is directly proportional to the product of the masses of the two objects and inversely proportional to the square of the distance between their centers of mass.
- To determine the gravitational force, we need to know the masses of the two objects. Let's call them m1 and m2.
- For the total mass of the objects, we add the masses of m1 and m2: Total mass = m1 + m2.
- The distance between the centers of the two objects is given as 4m.
- The velocity of m2 is not provided in the question, so we cannot determine it without additional information.
