Thanks I'll give that an attempt
Another question. Is it possible that the planet with radius R have different masses?
Ex.
GM/2R2=Gm/R2
I feel that this is wrong because of the fact that the planet is at constant density. Therefore at Radius R it must have mass M.
Homework Statement
A constant-density planet of radius R has a gravitational acceleration ag =
as at its surface. There are two distances from the center of the planet at
which ag = as/2. Show that the ratio of these distances may be given by
R = 2√2
Homework Equations
ag= GM/R2...
