Answer
given,
mass of an object = 5 Kg
mass of the other object = 5.98 x 10²⁴ Kg
radius of earth = 6371 Km = 6.371 x 10⁶ m
comparison between gravitational force between two object and weight of the object.
gravitational force between two objects
[tex]F = \dfrac{Gm_1m_2}{r^2}[/tex]
[tex]F = \dfrac{6.67 \times 10^{-11}\times 5 \times 5.98 \times 10^{24}}{(6.371 \times 10^6)^2}[/tex]
F = 49.134 N
weight of the object on the earth surface
F = m g
F = 5 x 9.81
F = 49.05 N
From the above two calculation we can conclude that gravitational force is approximately equal to weight of the body.
