The force of attraction between the spheres.
Answer to Problem 68A
Explanation of Solution
Given:
The weight of the first sphere is
The weight of the second sphere is
The distance between the spheres is
Formula used:
Gravitational force:
Where,
The weight of an object of mass m on the planet is:
Where, g is the gravitational strength on the planet.
Calculation:
Using the above formula and the known value of g on Earth, the mass of the spheres will be,
The value of gravitational constant is,
Then, the gravitational force between the spheres is,
Conclusion:
Thus, the gravitational force between the spheres is
