Identify the correct statement(s)a)The friction force acting on the cy...
Friction Forces on Cylinder and Ring:
The statement in option B is correct, which states that the friction force acting on the ring may be more than that acting on the cylinder. This is because the friction force depends on the normal force and the coefficient of friction between the surfaces in contact. The normal force is the force exerted perpendicular to the surface of contact. In the case of a ring and a cylinder, the normal force is distributed differently on each object.
Friction Force and Rolling Motion:
When an object rolls without slipping, the point of contact between the object and the ground is stationary. This means that the friction force at the point of contact provides the necessary torque to keep the object rolling. The friction force also opposes the relative motion between the object and the ground.
Friction and Rolling of Cylinder and Ring:
The statement in option D is correct, which states that if the friction is sufficient to roll the ring, then the cylinder will also roll. This is because the ring and the cylinder are in contact with the ground at the same point, and the friction force at this point is the same for both objects. If the friction force is sufficient to initiate rolling for the ring, then it will also be sufficient for the cylinder.
However, the statement in option C is incorrect. If the friction force is sufficient to roll the cylinder, it does not necessarily mean that the ring will also roll. The ring and the cylinder have different moments of inertia about their respective axes of rotation. The moment of inertia depends on the distribution of mass in the object. Therefore, even if the friction force is sufficient for the cylinder to roll, the ring may still slide instead of rolling due to its different moment of inertia.
Summary:
- The friction force acting on the ring may be more than that acting on the cylinder.
- If the friction is sufficient to roll the ring, then the cylinder will also roll.
- If the friction is sufficient to roll the cylinder, it does not necessarily mean that the ring will also roll.
