Question

Assertion (A): The position of the centre of gravity of a body remains unchanged even when the body is deformed.

Reason (R): The centre of gravity of a freely suspended body always lies vertically below the point of suspension.

पर्याय

• Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion.

• Both Assertion (A) and Reason (R) are true but Reason (R) is not the correct explanation of Assertion.

• Assertion (A) is false, but Reason (R) is true.

• Assertion (A) is true, but Reason (R) is false.

Answer 1

Assertion (A) is false, but Reason (R) is true.

Explanation:

Deforming a body can change the distribution of its mass and therefore change the position of its centre of gravity; Assertion (A) is false. When a body is freely suspended and at rest, its centre of gravity lies vertically below the point of suspension, so Reason (R) is true.
