Question

Two spherical objects have masses of 350 kg and 750 kg. Their centers are separated
by a distance of 3.2 m. Find the gravitational attraction between them

Answer 1

Answer: $F=1.71(10)N^{-6} N$

Explanation:

According to Newton's law of Universal Gravitation we have:

$F=G\frac{(m_{1})(m_{2})}{d^2}$  

Where:

$F$ is the gravitational attraction force between the spherical objects

$G=6.674x10^{-11}\frac{m^{3}}{kgs^{2}}$is the gravitational constant

$m_{1}=350 kg$ is the mass of the first object

$m_{2}=750 kg$ is the mass of the second object

$d=3.2 m$ is the distance between the objects

Solving the equation:

$F=6.674x10^{-11}\frac{m^{3}}{kgs^{2}}\frac{(350 kg)(750 kg)}{(3.2 m)^2}$  

$F=1.71(10)N^{-6} N$ This is the gravitational attraction between both objects
