Question
The force of attraction (F) between two particles having masses m 1and m 2is given by _______. (If r is the distance between them and G is a universal constant)
The correct answer is
\(G\frac{m_1m_2}{r^2}\)
Newton’s law for point masses is \(F=Gm_1m_2/r^2\). It is proportional to both masses and inversely proportional to the square of their separation.
