Which of the following would have the greatest gravitational attraction?Atwo 3kg balls 3 meters apartBtwo 3 kg balls 5 meters apartCtwo 3 kg balls 10 meters apartDtwo 3 kg balls 1 meter apart
Solution
The gravitational attraction between two objects is determined by their masses and the distance between them. This relationship is described by Newton's law of universal gravitation, which states that the force between two objects is proportional to the product of their masses and inversely proportional to the square of the distance between them.
In this case, all the balls have the same mass (3 kg), so the only factor that changes is the distance between them. According to Newton's law, the closer the objects are, the greater the gravitational attraction between them.
Therefore, the two 3 kg balls 1 meter apart (option D) would have the greatest gravitational attraction.
