Question

Which of the following statements is true about the weight of an object?

• A. The weight of an object is same as its mass
• B. The weight of an object refers to its Inertia
• C. The weight of an object is the force with which it is attracted toward the earth.
• D. None of these

Answer 1

The correct option is C

The weight of an object is the force with which it is attracted toward the earth.

The explanation for the correct option:

1. Weight is the force exerted on a body as a result of the Earth's gravitational pull. As a force, it is a vector quantity.
2. A body's weight is the product of its mass and gravity's acceleration.
3. Weight is inversely proportional to the square of the distance from the Earth's center.
4. The weight of various celestial bodies varies as well. A body's weight on the moon, for example, will be less than its weight on Earth.
5. Body weight can be written as $W=mg$.

Hence, Option(C) is correct.

The explanation for incorrect options:

1. Body weight can be written as $W=mg$. So it can not same as mass.
2. Inertia is a measure of an object's resistance to changes in its state of motion or rest that is proportional to its mass or amount of matter.

Hence, Option(C) is correct.
