Question
Which of the following exerts gravity? A. any object with mass B. only objects on Earth C. only planets, moons, and stars D. only the Earth
Solution
The correct answer is A. any object with mass. This is because gravity is a force that exists between any two masses, any two bodies, any two particles. It is mathematically described as: F = G (m1m2)/r^2, where F is the force of attraction between the two bodies, m1 and m2 are the two masses, r is the distance between the centers of the two masses, and G is the gravitational constant. Therefore, any object that has mass, regardless of its location, exerts a gravitational pull.
