Which of the following statement is correct?

Options

A. Gravitational force is always attractive in nature
B. Gravitational force is strongest in nature
C. Gravitational force is non-central force
D. Both (1) and (2)

Answer

To determine which statement is correct regarding gravitational forces, let's analyze each option step by step.

### Step 1: Analyze Option 1
**Statement:** Gravitational force is always attractive in nature.
- Gravitational force acts between two masses, M1 and M2, separated by a distance d.
- The formula for gravitational force is given by:
\[ F = \frac{G \cdot M1 \cdot M2}{d^2} \]
where G is the universal gravitational constant.
- According to Newton's law of gravitation, this force is always attractive, meaning M1 attracts M2 and M2 attracts M1 with equal and opposite forces.
- **Conclusion:** This statement is correct.

### Step 2: Analyze Option 2
**Statement:** Gravitational forces are strongest in nature.
- There are four fundamental forces in nature:
1. Gravitational Force
2. Electromagnetic Force
3. Weak Nuclear Force
4. Strong Nuclear Force
- Among these, the strong nuclear force is the strongest, followed by electromagnetic force, weak nuclear force, and finally, gravitational force, which is the weakest.
- **Conclusion:** This statement is incorrect.

### Step 3: Analyze Option 3
**Statement:** Gravitational forces are non-central forces.
- Central forces are those that act along the line joining the centers of two bodies.
- Gravitational forces act along the line connecting the centers of the two masses (M1 and M2) and depend on their distance.
- Therefore, gravitational forces are indeed central forces.
- **Conclusion:** This statement is incorrect.

### Final Conclusion
- The only correct statement is Option 1: Gravitational force is always attractive in nature.
