Question

Calculate the force of gravitation between two objects of masses 80 kg and 120 kg kept at a distance of 10 m from each other. Given, G = 6.67 × 10^-11 Nm² / kg².

Answer 1

m₁ = 80 kg, m₂ = 120 kg, r = 10 m, 

G = 6.67 × 10^-11 Nm² / kg², F = ?

F = \(\frac{Gm_1m_2}{r_2}\)

 = \(\frac{6.67 \times 10^{-11} \times 80 \times 120}{(10)^2}\)

= 64.032 x 10^-10 N

The force of gravitation between two objects = 64.032 x 10^-10 N.
