Given below are two statements, one labelled as Assertion (A) and the other labelled as Reason (R). Read the statements and choose the correct answer using the code given below.

Assertion (A): The layout position of gymnast makes it more difficult to somersault.

Reason (R): An extended gymnast has a greater moment of inertia than a piked gymnast.

 Key Points

Assertion: The layout position of a gymnast makes it more difficult to somersault.

Explanation:

• Assertion A states that the layout position, where the gymnast maintains a straight body position, makes it more challenging to perform a somersault.
• In gymnastics, a somersault involves rotating the body in a forward or backward motion while maintaining control and proper technique.
• The layout position requires the gymnast to keep the body extended and straight, which increases the difficulty of initiating and controlling the rotational movement.

Reason: An extended gymnast has a greater moment of inertia than a piked gymnast.

Explanation:

• Reason R provides an explanation for Assertion A by stating that an extended gymnast has a greater moment of inertia compared to a piked gymnast.
• Moment of inertia is a property that determines an object's resistance to rotational motion.
• In the layout position, the gymnast's body is extended, resulting in a greater distribution of mass away from the axis of rotation.
• This increased distribution of mass leads to a higher moment of inertia, which makes it more challenging to initiate and control the rotational movement required for a somersault.

The correct answer is Both (A) and (R) are true, and (R) is the correct explanation of (A).

This means that both statements are individually true, and Reason R provides a valid explanation for Assertion A, linking the difficulty of somersaulting in the layout position to the greater moment of inertia associated with an extended body position.
