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 problem, we need to analyze the behavior of an object placed in stable equilibrium when it is given a light push. Here’s a step-by-step solution:

### Step-by-Step Solution:

1. **Understanding Stable Equilibrium**:
- An object is in stable equilibrium when its center of gravity is at a minimum height. This means that if the object is displaced slightly, it will tend to return to its original position.

2. **Effect of a Light Push**:
- When a light push is applied to the object, it is displaced slightly from its equilibrium position.

3. **Movement of Center of Gravity**:
- As the object is pushed, the center of gravity will initially rise. This is because the object will tilt or rotate about its pivot point (the edge of the base in contact with the ground).

4. **Transition to Unstable Equilibrium**:
- After the push, the center of gravity moves higher than its original position. This creates a situation where the object is now in unstable equilibrium. If the push is sufficient, the object may continue to tip over.

5. **Conclusion**:
- Therefore, after the light push, the initial position of the center of gravity rises above the ground.

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