Homework Statement
In this problem find the force of gravity of Al. Al is standing at the top of Mt. Everest at an elevation of 8,848 m. Al has a mass of 58 kg. The Earth has a mass of 5.97e24 and a radius of 6.38e6m. What is the force of gravity acting on Al?
Homework Equations
F = GMm/r^2
The Attempt at a Solution
the dist. used to find F is from Al to the Earth's center ?
so r = 8848+6.38e6 ?
then plug in values
F = G 58(5.97e24)/(8848+6.38e6)^2
F[tex]\approx[/tex]569.385 N?
Is this right? I feel like I'm missing soemthing
