If you somehow increased Earth's radius, without changing its mass, would this affect your weight?
A) Yes, your weight would decrease.
B) No, because your weight always remains the same regardless of how you change the external surroundings.
C) Yes, your weight would increase.
D) No, because the force of gravity on your body depends only on your mass and on Earth's total mass-- it doesn't depend on Earth's size.
