Step 1: Understanding Mass and Weight
Mass is the quantity of matter in an object and is independent of the location of the object.
Weight is the force exerted on an object due to gravity, calculated as \( W = mg \), where \( m \) is mass and \( g \) is the gravitational acceleration.
Step 2: Effect of Loss of Gravity
If the Earth loses its gravity, the acceleration due to gravity (\( g \)) would become zero.
Therefore, the weight of any object will become zero.
However, the mass of the object remains unchanged because mass is independent of gravity.
Step 3: Conclusion
Thus, if the Earth loses its gravity, the body’s weight becomes zero, but its mass remains the same.
