Q. Two objects of mass 10 kg and 35 kg are 50 m apart from each other. The force acting between two objects at any instant of time is
(A) 2 $\times {10}^{-11} N$                            (B) 1.2 $\times {10}^{-11} N$
(C) 2.2 $\times {10}^{-11} N$                         (D) 0.934 $\times {10}^{-11} N$
(E) None of these

Dear Student,
                       As given in the question, m₁= 10 kg,  m₂ = 35 kg and  distance between them, r = 50m.
                   So, the force between masses,
                                                                        $F=\frac{G{m}_1{m}_2}{r^2}$
                                                                           =$\frac{6.67\times {10}^{-11}\times 10\times 35}{(50{)}^2}$
                                                                          =$$\begin{gathered} \frac{233.45\times {10}^{-10}}{2500} \\ =0.934\times {10}^{-11}N \end{gathered}$$
Hence correct option is (D)
