Identify the correct proportional relationship expressed by Newton’s law of universal gravitation for two point masses

m_1

and

m_2

separated by distance

r

. (a)

F \propto \dfrac{m_1 m_2}{r}

(b)

F \propto \dfrac{m_1 m_2}{r^2}

(c)

F \propto \dfrac{m_1+m_2}{r^2}

(d)

F \propto \dfrac{m_1 m_2}{r^3}
