The correct Answer is:
To analyze the given assertion and reason, we will break down the statements step by step. ### Step 1: Understand the Assertion The assertion states: "When we change the unit of measurement of a quantity, its numerical value changes." - This is true. When we convert a quantity from one unit to another, the numerical value associated with that quantity will change. **Example:** - If we have a length of 1 meter, converting this to centimeters gives us 100 centimeters. Here, the unit has changed from meters to centimeters, and the numerical value has changed from 1 to 100. ### Step 2: Understand the Reason The reason states: "Smaller the unit of measurement, smaller is its numerical value." - This statement is misleading. While it may seem intuitive that smaller units would correspond to smaller numerical values, this is not always the case. **Example:** - Consider mass: 1 kilogram (kg) is equal to 1000 grams (g). Here, the kilogram is a larger unit than the gram, yet its numerical value (1) is smaller than that of grams (1000). ### Step 3: Conclusion - The assertion is true: changing the unit of measurement does change the numerical value. - The reason is false: smaller units do not necessarily mean smaller numerical values. ### Final Answer - The correct option is: Assertion is true, but the reason is false. ---
To analyze the given assertion and reason, we will break down the statements step by step. ### Step 1: Understand the Assertion The assertion states: "When we change the unit of measurement of a quantity, its numerical value changes." - This is true.
