Answer:
[tex]\frac{W}{F} = 8.8\times10^7[/tex]
Explanation:
According to newton's law of gravitation
[tex]F=G\frac{m_1\times m_2}{r^2}[/tex]
here m_1=m_2=15000 kg
r= 3 meters and G= 6.67[tex]6.67\times10^{-11}[/tex]
putting values we get
[tex]F= 6.67\times10^{-11}\frac{15000^2}{3^2}[/tex]
solving the above equation we get
Force of gravitation F= [tex]1.6675\times 10^{-3}[/tex] newton
weight of the one of the truck W = mg= 15000×9.81 N
=147000 N
therefore [tex]\frac{W}{F} = \frac{147000}{1.66\times10^{-3}}[/tex]
=8.8×10^{7)
