What is the gravitational force fg between the two objects described in part b if the distance between them is only 50 km ?

Explanation:

The question is incomplete.

The complete question would be

B) Suppose the magnitude of the gravitational force between two spherical objects is 2000 N when they are 100 km apart. What is the gravitational force between the two objects described in Part B if the distance between them is only 50 km.

Given gravitational force between two object when objects are placed apart.

We need to determine gravitational force when they are kept apart.

As we know the gravitational force is inversely proportional to the square of distance between objects .

Where that will be constant. Because the mass of the object remain same in both cases. And is already gravitational constant.

Given,

Let is the force between objects when they were kept apart.

So, is the gravitational force when two objects were kept apart.

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.
