How much would your weight decrease if you went into space 3x the earths radius?
Isn' the force of gravity proportional to distance squared?
I am uncertain what into space 3x radiusearth means? is that the altitude, or the distance from the center of the Earth?
If altitude, 1/3^2 is how much it decreases.
If distance from center of earth, 1/4^2
