Quizplus · Accepted Answer

Weight is proportional to mass, so if the mass of the Earth decreased to one-half its original mass, then your weight would also decrease to one-half your original weight. This can be calculated using the equation: Weight = Mass x Gravity. Since the radius is not changing, gravity would remain the same, so the only factor affecting weight would be the decrease in mass. Therefore, your weight would decrease to one-half your original weight.
