Gravitational force is a fundamental force of nature that exists between any two objects with mass. It is responsible for the attraction between objects and plays a crucial role in the dynamics of celestial bodies, such as planets, stars, and galaxies. Let's analyze each statement and determine their correctness.
1. Gravitation is a property of only the earth.
This statement is incorrect. Gravitational force is not limited to the Earth; it is a universal force that exists between all objects with mass. The force of gravity can be observed on Earth, but it also applies to celestial bodies like the Sun, Moon, and planets. Furthermore, the gravitational force between objects decreases with distance, following the inverse square law.
2. All the objects of the universe apply gravitational force on each other.
This statement is correct. According to Newton's law of universal gravitation, every object with mass attracts every other object with mass. The magnitude of the gravitational force between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. Therefore, all objects in the universe, regardless of their size or distance from each other, exert gravitational forces on one another.
3. Gravitational force is responsible for water in rivers to flow downstream.
This statement is correct. Gravitational force plays a significant role in the flow of water in rivers. The force of gravity causes water to flow from higher elevations to lower elevations, creating a downstream flow. This effect is essential in the hydrological cycle, where water moves from precipitation in higher areas to rivers and eventually to the oceans. Gravity acts as the driving force behind this movement, ensuring the continuous flow of water.
In conclusion, statements 2 and 3 are correct, while statement 1 is incorrect. Gravitational force is a universal force that applies to all objects in the universe, and it is responsible for the downstream flow of water in rivers.

Gravitation is not the property of only Earth. In reality, all the objects of the universe apply force on each other, regardless of their size. Gravitational force is responsible for the water in rivers to flow downstream.
