● If Earth Somehow Expanded To A Larger Radius, With No Change In Mass, How Would Your Weight Be Affected? How Would It Be Affected If Earth Instead Shrunk? (Hint: Let The Equation For Gravitational Force Guide Your Thinking.)

If there is no change in mass of the earth, and only increase in the radius, then our weight will be the same at the point, but lesser at the point away from the centre of the earth. If the earth shrunk, then the weight of any body on its surface won't change. Let me know if its wrong, yeah?
