Question

Calculate the force of gravitation between two objects of masses 80kg and 1200 kg kept at a distance of 10 m from each other. Given G = 6.67 x 10–11 Nm2/kg2

Answer 1

Given,

m₁ = 80 kg

m₂ = 1200 kg

r = 10 m

We know that, According  to newton's  law of gravitation , Force  between two masses of  m₁ and m₂ which is placed  r m apart is,

$F=G\;\frac{m_1m_2}{r^{2}}\\ \\F=6.67\times11^{-11}\;\frac{80\times\;1200}{10}\\ \\F =64032\times10^{-11}\\ \\F=6.4032\times10^{-7}\;N$
