A body falls freely from a height 'h' after two seconds if we assume that gravity disappears the body

Options

A. continues to fall down with uniform velocity
B. falls down with acceleration
C. falls down & floats
D. falls down with declaration.

Answer

To solve the problem, we need to analyze the motion of a body falling freely from a height 'h' for 2 seconds, and then consider what happens when gravity disappears.

### Step-by-Step Solution:

1. **Understanding Free Fall**:
- When a body falls freely under the influence of gravity, it accelerates downwards. The acceleration due to gravity (g) is approximately 9.81 m/s².

2. **Velocity After 2 Seconds**:
- The velocity (v) of the body after falling for 2 seconds can be calculated using the formula:
\[ v = u + gt \]
where:
- \( u = 0 \) (initial velocity, since it starts from rest),
- \( g = 9.81 \, \text{m/s}^2 \) (acceleration due to gravity),
- \( t = 2 \, \text{s} \).
- Substituting the values:
\[ v = 0 + (9.81 \, \text{m/s}^2)(2 \, \text{s}) = 19.62 \, \text{m/s} \]

3. **Condition When Gravity Disappears**:
- After 2 seconds, if we assume that gravity disappears, the body will no longer experience any acceleration. This means that the acceleration (a) becomes 0.

4. **Motion After Gravity Disappears**:
- When the gravitational force disappears, the body will continue to move with the velocity it had just before gravity disappeared. Since there is no acceleration acting on it, the velocity remains constant.

5. **Conclusion**:
- Therefore, the body will continue to fall down with uniform velocity after gravity disappears.

### Final Answer:
The correct option is: **It continues to fall down with uniform velocity.**
