Question

If Earth's mass doubled, your weight would..

a. increase
b. decrease
c. stay the same

Answer 1

a. increase

Step-by-step explanation:

Doubling the mass of the Earth would double your weight, since gravitational force is directly proportional to mass, but doubling the radius (which doubles if the diameter doubles) would decrease your weight by a factor of 1/4, since gravitational force is inversely proportional to the square of the radius.
