By what factor would your weight change if Earth's diameter were quintupled and its mass was halved?
If the mass of Earth increased, your weight would correspondingly increase. But, if the mass of the Sun increased, your weight would not be affected at all. Why?
if earth shrank until its diameter were only 1/4 its present size without changing its mass, what would a 1kg mass weigh at its surface?
