Answer to Question #17166 in Mechanics | Relativity for Janine

Question #17166
By what factor would your weight change if Earth's diameter were tripled and its mass were quintupled?
Expert's answer
W = your weight
G = gravitational constant
M = mass of Earth
m = mass of you
r = radius of Earth

W = GmM/r²

if the diameter of Earth were halved, so would be its radius
so your weight with radius halved and mass quintupled would be

W_new = Gm(5M)/(½r)² = 5GmM/(¼r²) = 20W_old
