Answer:- The magnitude of the gravitational force of attraction between two uniform spheres, each with mass m and radius r, touching one another is:
F = G * m * m / (r^2)
where:
- F is the force of gravity
- G is the gravitational constant (6.67408 × 10^-11 N m^2 kg^-2)
- m is the mass of each sphere
- r is the radius of each sphere
The force of gravity is always attractive, and it increases as the masses of the two objects increase. The force of gravity also decreases as the distance between the two objects increases. In this case, the spheres are touching, so the distance between their centers is equal to the sum of their radii.
The gravitational force between the two spheres is directed along the line connecting their centers. The force is equal and opposite on each sphere, so each sphere experiences a force of magnitude F.
