1. The problem statement, all variables and given/known data An object is located a distance d above the surface of a large planet of radius r. At this position, its true weight is one percent (1.000 %) less than its true weight on the surface. What is the ratio of d/r? 2. Relevant equations 3. The attempt at a solution so if something weights 100 kg on the earth, at 'that' distance, it should weigh 99k. so d should be extremely small compared to R. D/R should be a big number then. But I have no idea how to put this into calculations.
