उत्तर

Given : r = 1 m, m1 = 75 kg, m2 = 80 kg 
and G = 6.67 x 10 -11 Nm2/kg2
According to Newton’s law 

                                     `F  = (Gm_1m_2)/(r^2)`

                                    `F=(6.67 xx 10^(-11) xx 75 xx80)/1^2 n`

                                   ` = 4.002 xx 10^-7 N`

The gravitational force between Mahendra and Virat is 4.002 x 10-7
