the distance b/w moon & earth is r2 how plz tell me if any one know correctly
Answers
Answer:
The gravitation constant (G) in Nm2/Kg2.
The mass of object 1 (m1), in this case the mass of earth in kilograms (Kg).
The mass of object 2 (m2), in the case the mass of earth's moon in kilograms (Kg).
The average distance from the center of the earth to the center of the moon in meters (m).
Now that you have acquired the proper information for the equation, calculate the gravitational force between the earth and moon.
F= (G x m1 x m2) / r2 =
The gravitational force between the earth and moon at the average distance between them may be expressed as F. For the following changes in mass or distance or both, will the value of F remain constant, increase, or be reduced? Calculate F for each of the following changes; it is understood that the factors not mentioned remain unchanged:
The moon's mass is doubled.
The earth's mass is doubled.
Both the mass of the earth and that of the moon are doubled.
The distance between the centers of the two are doubled.
Both masses are doubled and the distance is halved.
