The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Problem**: The question states that food particles can sometimes enter the windpipe (trachea) instead of the esophagus (food pipe). This can lead to choking, which is a serious situation. 2. **Identifying the Body's Response**: When food particles enter the windpipe, it creates an obstruction in the respiratory tract. The body has mechanisms to respond to such obstructions. 3. **Role of the Medulla Oblongata**: The medulla oblongata is a part of the brain that controls various involuntary functions, including the respiratory center. When an obstruction occurs, it sends signals to the medulla oblongata. 4. **Cough Reflex**: The medulla oblongata activates the cough center in response to the obstruction. This initiates the cough reflex, which is a protective mechanism to expel foreign particles from the respiratory tract. 5. **Expulsion of Food Particles**: Through the process of coughing, the food particles that entered the windpipe are expelled out from the mouth, thereby clearing the airway. 6. **Conclusion**: The correct answer to the question is that food particles that enter the windpipe are expelled by the process of **coughing**. **Final Answer**: Coughing (Option B). ---

When a particle is projected at some angle with the horizontal, the path of the particle is parabolic. In the process the horizontal velocity remains constant but the magnitude of vertical velocity changes. At any instant during flight the acceleration of the particle remains g in vertically downward direction. During flight at any point the path of particle can be considered as a part of circle and radius of that circle is called the radius of curvature of the path Consider that a particle is projected with velocity u=10 m//s at an angle theta=60^(@) with the horizontal and take value of g=10m//s^(2) . Now answer the following questions. The radius of curvature of path of particle at the instant when the velocity vector of the particle becomes perpendicular to initial velocity vector is
