1. A planet has a mass 1/2 that of Earth and a radius 2 times that of Earth. What is the acceleration due to gravity on the surface of the planet in terms of g?
2.
a)F=G*m1*m2/r[tex]^{2}[/tex]
b)F=mg
3. I figured that I would let the two equations equal to each other so...
G*m1*m2/r[tex]^{2}[/tex]=mg
It simplifies to be g=G*m/r[tex]^{2}[/tex]
However, I don't know where to go from there to get the acceleration in terms of g.
Any suggestions would be greatly appreciated. Thanks
