Question

Two spherical objects have masses of 1.5 x 10^5 kg and 8.5 x 10^2 kg. Their centers are separated by a distance of 2500 m. Find the gravitational attraction between them.

Answer 1

1.36 x 10^(-9) N

Step-by-step explanation:

The gravitational attraction between two objects can be calculated as

`F=G(m_1m_2)/(r^2)`

Where G is a constant equal to 6.67 x 10^(-11) m³/kg·s², m1 and m2 are the masses of the objects and r is the distance between them. So, replacing the values, we get:

`\begin{gathered} F=(6.67*10^(-11))((1.5*10^5)(8.5*10^2))/(2500^2) \\ F=1.36*10^(-9)N \end{gathered}`

Therefore, the gravitational attraction between them is 1.36 x 10^(-9) N
