Question

If the earth loses its gravity, then for a body _______

• A. Weight becomes zero
• B. Mass becomes zero
• C. Neither mass nor weight is zero
• D. Both mass and weight are zero

Answer 1

Answer: (A)

Weight becomes zero

Answer 2

Mass (m) is an intrinsic property of a body, representing the amount of matter it contains. It does not depend on the presence or absence of a gravitational field. Therefore, if the Earth loses its gravity, the mass of a body remains unchanged.

Weight (W) is the force exerted on a body due to gravity, calculated as $W = mg$, where 'm' is the mass and 'g' is the acceleration due to gravity.

If the Earth loses its gravity, the acceleration due to gravity 'g' becomes zero ($g=0$).

Consequently, the weight of a body becomes $W = m \times 0 = 0$.

Thus, if the Earth loses its gravity, the weight of a body becomes zero, while its mass remains constant (non-zero).
