Question

Calculate the gravitational force between two bodies ${}^{\prime }{a}^{\prime }$ and ${}^{\prime }{b}^{\prime }$ of mass $50kg$ each at a distance of $1m$ from each other.

Answer 1

Given:

Mass of the body $a$ is $m_a=50kg$

Mass of the body $b$ is $m_b=50kg$

Distance between $a$ and $b$ is $d=1m$

Gravitational force $\left(F_G\right)=\frac{G{m}_a{m}_b}{d^2}$

$=(6.67\times {10}^{-11})\frac{50\times 50}{1^2}$

$=1.6675\times {10}^{-7}N$
