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

Answer:

1.36 x 10^(-9) N

Explanation:

The gravitational attraction between two objects can be calculated as

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

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:

$\begin{gathered} F=(6.67\times10^{-11})\frac{(1.5\times10^5)(8.5\times10^2)}{2500^2} \\ F=1.36\times10^{-9}N \end{gathered}$

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