1. How does the force of gravitation between two objects change when the distance between them is reduced to half?Ans. The force of gravitation between two objects is inversely proportional to the square of the distance between them therefore the gravity will become four times if distance between them is reduced to half. 2. Gravitational force acts on all objects in proportion to their masses. Why then, a heavy object does not fall faster than a light object?Ans. In free fall of objects the acceleration in velocity due to gravity is independent of mass of those objects hence a heavy object does not fall faster than a light object. 3. What is the magnitude of the gravitational force between the earth and a 1 kg object on its surface? (Mass of the earth is |
