Answer:
= 4.688 106 m
Explanation:
The expression for the center of mass is
R cm = 1 / M ∑
Where M is the total mass of the system, ri and m1 are the distance and mass of each particle from a defined origin
Let's look for the total mass, the mass of the moon is m and that of the earth Me
M = + m
M = 81m + m
M = 82 m
The distance from the earth to the moon is R = 384.4 106 m
= 1 / M (M R1 + m R)
= 1 / 82m (0 + m R)
= R / 82
= 384.4 106/82
= 4.688 106 m
The radius of the earth is
= 6371 103 m
= 6.371 106 m
We can see that the center of mass of the system is within the beating radius
