It is general principle that the less energy a system constains, it is

Options

A. Less stable
B. More stable
C. Unstable
D. More unstable

Answer

To solve the question, we need to analyze the relationship between the energy of a system and its stability.

### Step-by-Step Solution:

1. **Understanding Stability and Energy**:
- Stability in a system is often related to the amount of energy it contains. Generally, systems with lower energy are more stable than those with higher energy.

2. **Potential Energy Example**:
- Consider two sticks: one is standing upright and the other is lying flat on the ground.
- The standing stick has a height above the ground, which means it has potential energy due to its position.

3. **Potential Energy Calculation**:
- The formula for potential energy (PE) is given by:
\[ PE = mgh \]
where \(m\) is mass, \(g\) is the acceleration due to gravity, and \(h\) is the height above the ground.
- In this case, both sticks have the same mass and are in the same gravitational field, but the height \(h\) is different.

4. **Comparing Energies**:
- The standing stick has a greater height \(h\) compared to the lying stick, which means it has more potential energy.
- Therefore, the lying stick, which is at ground level, has less potential energy and is more stable.

5. **Conclusion**:
- Since the stick lying on the ground has less energy, it is more stable than the standing stick.
- Thus, the general principle states that the less energy a system contains, the more stable it is.

### Final Answer:
The correct option is: **more stable**.
