The force of gravity between the astronauts is 
Explanation:
The magnitude of the gravitational force between two objects is given by:
 
where
:
 is the gravitational constant
 is the gravitational constant
 are the masses of the two objects
 are the masses of the two objects
r is the separation between them
In this problem, we have two astronauts, whose masses are:

While the separation between the astronauts is
r = 2 m
Substituting into the equation, we can find the gravitational force between the two astronauts:

Answer:
hi here is your answer and this is a very important question. 
Explanation:
A lever is a rigid bar with three parts: the fixed point around which the bar pivots is the fulcrum: the effort arm (in-lever arm) is the part of the lever to which force is applied; the resistance arm (out-lever arm) is the part that bears the load to be moved.
