Question

Which statement about the universality of gravity is untrue ?

1.the gravitational force between two objects increases if the distance between the objects decreases.

2.any two objects that have mass also have a force of gravity acting between them ,no matter how far apart they are

3.the gravitational force between two objects depends on their masses.

4.the gravitational force between two objects increases if the mass of one object increases

Answer 1

\(F=G\dfrac{m_1m_2}{r^2}\) thus \(F \propto \dfrac{1}{r^2}\)
