A cyclist taking turn bends inwards while a car passenger taking same turn is thrown outwards. The reason is

Options

A. car is heavier than cycle
B. car has four wheels while cycle has only two
C. difference in the speed of the two
D. cyclist has to counteract the centrifugal force while in the case of car only the passenger is thrown by this force

Answer

To understand why a cyclist bends inward while a car passenger is thrown outward when taking a turn, we can analyze the forces acting on both the cyclist and the car passenger.

### Step-by-Step Solution:

1. **Understanding the Scenario**:
- When a cyclist and a car take a turn, they are both moving along a circular path. The cyclist bends inward, while the car passenger feels as if they are being pushed outward.

2. **Centripetal Force**:
- For both the cyclist and the car, a centripetal force is required to keep them moving in a circular path. This force is directed towards the center of the circle.

3. **Centrifugal Force**:
- From the perspective of the car passenger, there is an apparent force acting outward, known as centrifugal force. This is not a real force but a result of inertia, as the passenger tends to move in a straight line while the car turns.

4. **Forces Acting on the Car Passenger**:
- In the car, the passenger experiences the centrifugal force pushing them outward. If the car does not provide sufficient friction or support, the passenger may feel like they are being thrown outward.

5. **Forces Acting on the Cyclist**:
- The cyclist, on the other hand, can lean inward while taking the turn. By bending at an angle, the cyclist creates a balance between the gravitational force and the centrifugal force. The normal force from the ground provides a component that counteracts the centrifugal force.

6. **Balancing Forces**:
- For the cyclist, the inward lean allows the normal force to have a component that balances the outward centrifugal force. This is why the cyclist bends inward to maintain balance and avoid being thrown outward.

7. **Conclusion**:
- The key difference is that the cyclist actively adjusts their position to counteract the centrifugal force, while the car passenger does not have the same ability to adjust and feels the outward force more acutely.

### Final Answer:
The reason a cyclist bends inward while a car passenger is thrown outward is that the cyclist can counteract the centrifugal force by leaning, while the car passenger experiences the centrifugal force without any means to counteract it.
