Question

Assertion: As the centre of gravity of a body is raised, the body becomes more unstable.

Reason: This happens because when the body is tilted, the vertical line is drawn from the centre of gravity outside the base.

Options

• If both Assertion and Reason are true and the Reason is correct explanation of the Assertion.

• If both Assertion and Reason are true, but Reason is not correct explanation of the Assertion.

• If Assertion is true, but the Reason is false.

• If Assertion is false, but the Reason is true.

Answer 1

If both Assertion and Reason are true and the Reason is correct explanation of the Assertion.

Explanation:

As the centre of gravity of a body is raised, the body becomes more unstable because it can topple more easily. Therefore, the Assertion (A) is true.

When the body is tilted, the vertical line through its centre of gravity can pass outside the base, causing the body to topple. Therefore, the Reason (R) is true and correctly explains the Assertion.

Hence, both A and R are true and R is the correct explanation of A.
