Answer to Question #204149 in Classical Mechanics for Mile

Question

Jake (80kg) and Mike (100kg) are standing 8 meters apart. What is the gravitational force between the two us us?

Answer 1

$m_1= 80$

$m_2 =100$

$r = 8$

$G= 6.67*10^{-11}$

$\vec F=G\frac{m_1m_2}{r^2}$

$\vec F=6.67*10^{-11}\frac{80*100}{64}\approx8.4*10^{-9}$

$\text{Answer: }\vec F\approx8.4*10^{-9}\ N$
