The distance from the center of the earth to a point where the acceleration due to gravity is g/16 is

none of the these.
4RE.
3RE.
16RE.
1/4RE.

• physics -

If one goes 4 RE, then gravity will be

F=GMm/(4re)^2

• physics -

I don't know what that means. Can you explain?

• physics -

I wonder if you know what g is...

F/m= g= GM/re^2

if you go out 4 re, then

F/m= GM/16re^2= g/16
