If the Earth were to suddenly double in mass but remained the same size (a sphere with the same radius), how would that change your weight?

Your weight would not be affected at all, since Earth’s size is the same.

Your weight would be twice as much as it was before since Earth's mass has doubled.

Your weight would be half as much as it was before since Earth's mass has doubled.

Your weight would be 4 times what it was before since Earth's mass has doubled.
