To solve this problem it is necessary to use the concepts related to the Gravitational Force and Newton's Second Law, as far as we know:
Where,
G = Gravitational constant
M = Mass of earth (in this case)
m = mass of satellite
r = radius
In the other hand we have the second's newton law:
Where,
m = mass
a = acceleration
Equation both equations we have,
For the problem we have that,
<em>Satellite A:</em>
<em>Satellite B:</em>
The ratio between the two satellites would be,
Solving for a_B,
Therefore the centripetal acceleration of is a quarter of
Answer:
1170 Kelvin/meter
