Answer:
r_{cm} = 4.67 10⁶ m
We see that none of the answers is correct, the closest is the third, but the center of mass is within the radius of the Earth
Explanation:
The definition of the center of mass is
= 1 / M ∑
Where M is the total mass, and
mi are the position and the mass gives each of the bodies
We must locate a reference system for the calculation, we will locate it with the origin in the center of the Earth, the data we have are
Mass of the Earth Me = 5.98 1024 kg
Moon mass m = 7.36 1022 kg
Earth to Moon Distance r = 3.84 108 m
Let's apply this to our case
r_{cm} = 1 / (Me + m) (Me 0 + m R)
r_{cm} = 1 / (598 +7.36) 10²² (0 + 7.36 10²² 3.84 10⁸)
r_{cm} = 4.67 10⁶ m
We can see that this distance is less than the radius of the Earth
