The value of acceleration due to gravity (g) on a point 10,000 kilometers above sea level is about 1.49 meters/second2. How much will an object, which weighs 98 newtons on the surface of Earth, weigh on this point? The value of acceleration due to gravity on Earth is 9.8 meters/second2
Weight = mass gravity
98 = m (9.81)
mass= 9.99 <-- mass of object that is on surface of earth
you want to find the weight of that same object at a different point. I found the mass so that I could apply it to the formula to find its weight at the point that they are asking for.
Weight = mass gravity
W = 9.99 * 9.81
W = 98.00
hope this helps :)
