An object placed on the ground in the stable equilibrium. If the object is given a light push, then initially the position of centre of gravity

Options

A. moves number of ground
B. rises higher above the ground
C. remains as such
D. may remain at same level

Answer

To solve the question regarding the behavior of an object in stable equilibrium when given a light push, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Stable Equilibrium**:
- In stable equilibrium, an object is at rest and will return to its original position after being slightly displaced. This occurs because the center of gravity (CG) is at its lowest point.

2. **Effect of a Light Push**:
- When the object is given a light push, it moves slightly from its equilibrium position. This displacement causes the center of gravity to rise momentarily.

3. **Potential Energy Consideration**:
- As the object is pushed, it gains potential energy because it is lifted to a higher position. The center of gravity moves upward as the object tilts or shifts.

4. **Restoration to Equilibrium**:
- After reaching the highest point due to the push, the object will start to lose potential energy. The gravitational force acting on it will cause it to return to its original position.

5. **Conclusion on Center of Gravity**:
- Initially, when the object is pushed, the center of gravity rises above its original position. However, it will eventually return to its original equilibrium position after oscillating back and forth.

### Final Answer:
- The initial position of the center of gravity rises above the ground when the object is given a light push.
