a satellite is orbiting a planet a distance r from its center and another satellite is orbiting at a distance 3r from its center. what is the relation between the accelerations due to gravity for each case?

Respuesta :

Answer:

The relation between acceleration due to gravity for both cases [tex]g_{1} = 9g_{2}[/tex]

Explanation:

What is acceleration due to gravity ?

Any object's acceleration when it is only being affected by gravity.

According to the given information

Acceleration due to gravity could be found by  [tex]\frac{GM}{r^{2} }[/tex]

Distance between satellite orbiting planet from center = r

Acceleration due to gravity for this case [tex]g_{1}[/tex] = [tex]\frac{GM}{r^{2} }[/tex]

Distance between satellite orbiting planet from center = 3r

Acceleration due to gravity for this case [tex]g_{2}[/tex] = [tex]\frac{GM}{(3r)^{2} }[/tex]

relation between the acceleration due gravity in each case

[tex]\frac{g_{1} }{g_{2} } =\frac{(3r)^{2} }{r^{2} } \\[/tex]

[tex]\frac{g_{1} }{g_{2} } =\frac{9r^{2} }{r^{2} } \\[/tex]

[tex]\frac{g_{1} }{g_{2} }[/tex] = 9

[tex]g_{1} = 9g_{2}[/tex]

The relation between acceleration due to gravity for both cases [tex]g_{1} = 9g_{2}[/tex]
