What two factors determine the force of gravity between two objects?
1 answer:
Answer:
Mass and distance between them are two factors on which force of gravity depends
Explanation:
According to law of gravitation
Gravitational force between two object is given by , here G is gravitational constant
are mass of the objects and r is distance between them
From the relation we can see that force of gravity is dependent on the mass of the objects and distance between them.
So mass and distance between them are two factors on which force of gravity depends

Answer:
x_{cm} = 4.644 10⁶ m
Explanation:
The center of mass is given by the equation
= 1 /
∑
Where M_{total} is the total masses of the system, is the distance between the particles and
is the masses of each body
Let's apply this equation to our problem
M = Me + m
M = 5.98 10²⁴ + 7.36 10²²
M = 605.36 10²² kg
Let's locate a reference system located in the center of the Earth
Let's calculate
x_{cm} = 1 / 605.36 10²² [Me 0 + 7.36 10²² 3.82 10⁸]
x_{cm} = 4.644 10⁶ m
