mass of two students are
[tex]m_1 = 61.5 kg[/tex]
[tex]m_2 = 70 kg[/tex]
distance between them is given as
[tex]r = 1.25 m[/tex]
now gravitational force between them is given as
[tex]F = \frac{Gm_1m_2}{r^2}[/tex]
now plug in all values
[tex]F = \frac{6.67\times 10^{-11} \times 61.5 \times 70}{1.25^2}[/tex]
[tex]F = 1.84 \times 10^{-7} N[/tex]
so above is the force of gravitation between them
