Given that,
Mass of an elephant, m₁ = 3600 kg
Mass of giraffe, m₂ = 822 kg
The distance between elephant and giraffe, d = 400 m
To find,
The force of gravity between two animals.
Solution,
The formula for the force of gravity is given by the formula as follows :
[tex]F=G\dfrac{m_1m_2}{r^2}\\\\F=6.67\times 10^{-11}\times \dfrac{3600\times 822}{(400)^2}\\\\=1.23\times 10^{-9}\ N[/tex]
So, the force of gravity is [tex]1.23\times 10^{-9}\ N[/tex].
