Among the following find the wrong statement

Options

A. Law of gravitation is framed using Newton.s third law of motion
B. Law of gravitation cannot explain why gravity exists.
C. Law of gravitation does not explain the presense of force even when the particles are not in physical contact.
D. When the range is long, gravitational force becomes repulsive

Answer

To solve the question of identifying the wrong statement among the provided options regarding the law of gravitation, we will analyze each statement step by step.

### Step-by-Step Solution:

1. **Evaluate Statement 1**:
- The first statement claims that the law of gravitation is framed using Newton's third law of motion.
- **Analysis**: Newton's third law states that for every action, there is an equal and opposite reaction. The gravitational force between two masses can be seen as an action-reaction pair, where mass m1 attracts mass m2 with a force, and mass m2 attracts mass m1 with an equal and opposite force.
- **Conclusion**: This statement is **true**.

2. **Evaluate Statement 2**:
- The second statement claims that the law of gravitation cannot explain why gravity exists.
- **Analysis**: The law of gravitation provides a mathematical expression for the gravitational force but does not delve into the underlying reasons for the existence of gravity itself. It simply describes how gravity behaves.
- **Conclusion**: This statement is **true**.

3. **Evaluate Statement 3**:
- The third statement states that the law of gravitation does not explain the presence of force even when the particles are not in physical contact.
- **Analysis**: The law of gravitation indeed describes the gravitational force acting at a distance without requiring physical contact between the masses. It quantifies the force based on the masses and the distance between them.
- **Conclusion**: This statement is **true**.

4. **Evaluate Statement 4**:
- The fourth statement claims that when the range is long, the gravitational force becomes repulsive.
- **Analysis**: The gravitational force is always attractive and does not become repulsive regardless of the distance between the two masses. The force is inversely proportional to the square of the distance, but it remains attractive at all distances.
- **Conclusion**: This statement is **false**.

### Final Answer:
The wrong statement among the options is **Statement 4**: "When the range is long, gravitational force becomes repulsive."
