Question

calculate the force of gravitation between two objects of mass 50kg and 120kg respectively kept at a distance of 10m from one another

Answer 1

Given,

m₁ = 50 kg

m₂ = 120 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,

$F=G\;\frac{m_1m_2}{r^{2}}\\ \\F=6.67\times11^{-11}\;\frac{50\times\;120}{10}\\ \\F =4002\times10^{-11}\\ \\F=4.002\times10^{-7}\;N$

Answer 2

Given,

m₁ = 50 kg

m₁ = 50 kgm₂ = 120 kg

m₁ = 50 kgm₂ = 120 kgr = 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,

$\tt\begin{lgathered}F=G\;\frac{m_1m_2}{r^{2}}\\ \\F=6.67\times11^{-11}\;\frac{50\times\;120}{10}\\ \\F =4002\times10^{-11}\\ \\F=4.002\times10^{-7}\;N\end{lgathered}$
