What is the distance from the Earth's center to a point outside the Earth where the gravitational acceleration due to the Earth is 1/14 of its value at the Earth's surface?

Remmeber that gravity forces are inversely proportional to the distance to the object's center of gravity squared. That is:
If you call the radius of the earth R, then the gravity at the earth's surface (where r=R) is 1/R^2. So you're interested in finding the value of r such that :
Can you take it from here?
Hello human09fishie
Have a look here for all data and explanation needed to calculate the distance - LINK
Success !
:)
