Action and reaction can never balance out because

Options

A. they are equal but not opposite always
B. they are unequal in magnitude even though opposite in direction
C. though they are equal in magnitude and opposite in direaction they act on different bodies
D. they are unequal in magnitudes

Answer

To solve the question "Action and reaction can never balance out because," we can analyze the options provided and understand the principles of Newton's Third Law of Motion.

### Step-by-Step Solution:

1. **Understanding Action and Reaction Forces**: According to Newton's Third Law of Motion, for every action, there is an equal and opposite reaction. This means that whenever one body exerts a force on another body, the second body exerts a force of equal magnitude and opposite direction back on the first body.

2. **Analyzing the Options**:
- **Option 1**: "They are equal but not opposite always."
- This option is incorrect because action and reaction forces are always equal and opposite.

- **Option 2**: "They are unequal in magnitude even though opposite in direction."
- This option is also incorrect because action and reaction forces are always equal in magnitude.

- **Option 3**: "They are equal in magnitude and opposite in direction; they act on different bodies."
- This option is correct. Action and reaction forces are equal in magnitude and opposite in direction, but they act on different bodies. Therefore, they cannot balance each other out.

3. **Conclusion**: Since action and reaction forces act on different bodies, they do not cancel each other out. This is why they can never balance out.

### Final Answer:
Action and reaction forces can never balance out because they are equal in magnitude and opposite in direction, but they act on different bodies.
