Question

Assertion:The mass of a substance is constant whereas its weight may vary from one place to another
Reason: Mass of a substance is the amount of matter present in it while weight is the force exerted by gravity on an object

• A. If both assertion and reason are true and reason is the correct explanation of assertion
• B. If both assertion and reason are true but reason is not the correct explanation of assertion
• C. If assertion is true but reason is false.
• D. If both assertion and reason are false

Answer 1

Answer: (A)

Mass is a measurement of the amount of matter something contains, while Weight is the measurement of the pull of gravity on an object. Therefore, the mass of a substance is constant whereas its weight may vary from one place to another depending on the gravitational pull. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
