One planet is 3.00 x 1012 kg and another is 2.00 x 1010 kg and they are separated by a distance of 10 x 1015 m. Calculate the gravitational force between the two planets.

The gravitational force between the two planets is

Explanation:

Newton’s Law of Universal Gravitation

Objects attract each other with a force that is proportional to their masses and inversely proportional to the square of the distance between them.  

Where:

m1 = mass of object 1

m2 = mass of object 2

r     = distance between the objects' center of masses

G   = gravitational constant:

The mass of the planets are:

And the distance is:

Applying the formula:

Calculating:

The gravitational force between the two planets is

graph slopes whilst gas cools, then it is flat whilst conensation to liquid happens, the coolong liquid then graphs as a slope when it solidifies graph is flat
