Direction: In the following questions, a statement of assertion (A) i...
Assertion and Reasoning:
Assertion: The height of an object is always considered positive.
Reasoning: An object is always placed above the principal axis in this upward direction.
Explanation:
Height is a scalar quantity that is always positive. When an object is placed above the principal axis, it is considered to be in the upward direction, and its height is measured from the principal axis. Therefore, the assertion is true. The reason for this assertion is also true since the principal axis is a reference line used to measure the height of an object. When an object is placed above this reference line, it is considered to be in the upward direction, and its height is measured as a positive value.
Option A:
Both the assertion and reasoning are true, and the reasoning correctly explains the assertion. Therefore, option A is the correct answer.
Option B:
Both the assertion and reasoning are true, but the reasoning does not correctly explain the assertion. Therefore, option B is incorrect.
Option C:
The assertion is true, but the reasoning is false. Therefore, option C is incorrect.
Option D:
The assertion is false, but the reasoning is true. Therefore, option D is incorrect.
Option E:
Both the assertion and reasoning are false. Therefore, option E is incorrect.
Therefore, the correct option is (A).
