What is the gravitational force between two identical 50,000kg asteriods whose centre of mass are separated by 1000m?
Answers
Answer:
F = G*Mm/r^2
Explanation:F = 6.64*10^-11 * 50000*50000/1000*1000
F= 0.166 N
**I am not sure of the calc but, this is the formula,verify the calc once......
Answer:

Explanation:
For this,you must know how to behave with Scientific Notations
Use the Newton's law of Gravitation formula
F
=
G

=
Mass of second object=
5000 kg
r
=
Distance between the centres of the objects
=
100 m
We need to find
F
Before entering the values, we must convert the mass and the distance values into scientific notation (in the form of exponents)

=
5000 kg
