Question

Suppose the gravitational attraction of earth suddenly disappears, then

• A. weight of body becomes zero but mass remains unchanged
• B. weight and mass of body both becomes zero
• C. weight and mass of body both remains unchanged
• D. weight of body remains unchanged but mass becomes zero of weight

Answer 1

The correct option is A

weight of body becomes zero but mass remains unchanged

Explanation for the correct option(s):

(A): weight of body becomes zero but mass remains unchanged

1. Mass: It is a quantitative measure of inertia and the most fundamental property of all matter or thequantity of matter present in a body.
2. Mass is independent of acceleration due to gravity.
3. Hence, even if gravitational force on earth disappears, there will be no effect on the mass of the body.
4. Weight: It can be defined as the force exerted on a body due to gravitational force on a body.
5. If the gravitational force on earth disappears, then there would be no force acting on a body downwards.
6. Thus, weight of the body will become zero.

Therefore, option (A) is correct.
