Question

If the Earth loses its gravitational pull, what will happen to the weight and mass of an object?

• A. The mass will become zero, but the weight will not.
• B. The weight will become zero, but the mass will not.
• C. Both weight and mass will become zero.
• D. Neither the weight nor the mass will become zero.

Hint:

In the absence of gravity, weight becomes zero, but mass is not typically considered to exist without gravity.

Answer 1

The Correct Option is A

If the Earth loses its gravitational pull, the concept of weight and mass would change significantly.
Weight: Weight is the force exerted by gravity on an object and is given by: \[ W = mg \] where \( W \) is weight, \( m \) is the mass, and \( g \) is the acceleration due to gravity. If gravity is completely absent, the weight of the object becomes zero.
Mass: Mass is a measure of the amount of matter in an object and remains unaffected by gravity. However, without gravity, mass would not exist in the conventional sense. In a universe without gravity, mass itself would be undefined because it requires a reference to the gravitational field.

Thus, in such a scenario, the mass becomes zero, and the weight would not.
