Please help i will give brainliest In thinking about the uniform distribution of a gravitational field over a sphere, why does gravitational force have an inverse-square relationship with the distance between objects?

because the volume of a sphere is proportional to its radius

because the surface area of a sphere is proportional to the square of its radius

because the volume of a sphere is proportional to the square of its radius

because the surface area of a sphere is proportional to its radius

What happens to the gravitational force between two objects if the distance between them triples?

The force increases by a factor of 9.

The force increases by a factor of 3.

The force decreases by a factor of 9.

The force decreases by a factor of 3.

What must be the units for the gravitational constant G in order for gravitational force to have units of newtons?

m3/(kg⋅s)

m3/(kg⋅s2)

m3/(kg2⋅s)

m3/(kg2⋅s2)
