Question

Calculate the gravitional force between two body A and B having mass 50kg each and at the distance of 1m from each other

Answer 1

Given,

m₁ = m₂ = 50 kg

r = 1 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,

$F=G\;\frac{m_1m_2}{r^{2}}\\ \\F=6.67\times11^{-11}\;\frac{50\times\;50}{1}\\ \\F = \frac{16675}{1}\times10^{-11}\\ \\F=1.6675\times10^{-7}\;N$
