Question

The mass of an object

• A. Can be measured using a spring balance
• B. Remains constant
• C. Is in the direction of gravitational force
• D. Varies at different locations

Answer 1

The correct option is B

Remains constant

Mass: Mass is the amount of matter. Mass depends completely on the molecules an object is made of and the number of atoms in that object.

Explanation for correct answer:

• Option B. remains constant, It is clear from the definition that the mass completely depends on the quantity and type of molecule its made of, so it remains constant everywhere in the universe.

Explanation for incorrect answers:

• Option A, We can measure the weight of an object using spring balance but not mass directly, we can measure mass if we know the gravitational force at that particular spot but as we know gravity keeps varying at different spots so, we can't measure it accurately.
• Option C, Weight is in the direction of the gravitational field but not mass
• Option D, Weight varies at different locations as it depends on gravity which varies at different locations but the mass remains constant throughout the universe.

Hence, only option B is correct.
