The gravitational force of earth on a ball is 10 N then the gravitational force of attraction of the ball on the earth is

Options

A. 10 N
B. zero
C. slightly less than 10 N
D. more than 10 N

Explanation

To solve the question, we need to understand the concept of gravitational force and Newton's Third Law of Motion. Here's a step-by-step solution:

### Step-by-Step Solution:

1. **Understanding Gravitational Force**:
- The gravitational force is the force with which the Earth attracts an object towards itself. In this case, the gravitational force of Earth on the ball is given as 10 N.

2. **Applying Newton's Third Law of Motion**:
- According to Newton's Third Law, for every action, there is an equal and opposite reaction. This means that if the Earth exerts a force on the ball, the ball exerts an equal force back on the Earth.

3. **Identifying the Forces**:
- The gravitational force of the Earth on the ball is 10 N (action).
- Therefore, the gravitational force of the ball on the Earth (reaction) must also be equal in magnitude but opposite in direction.

4. **Conclusion**:
- Since the gravitational force of the Earth on the ball is 10 N, the gravitational force of attraction of the ball on the Earth is also 10 N.

### Final Answer:
The gravitational force of attraction of the ball on the Earth is **10 N**.
