Question

Two spherical objects have masses of 300 kg and 1000 kg. A distance of 5 m separates their centers. Find the gravitational attraction between them.

Answer 1

`8\cdot10^(-7)N`

Step-by-step explanation

We want to find the force of gravitational attraction between the two objects.

To do this, apply the formula for gravitational force between two objects:

`F=(Gm_1m_2)/(r^2)`

where G = gravitational constant

m1 = mass of the first object

m2 = mass of the second object

r = distance between the centers of mass of the two objects.

Hence, the force of gravitational attraction between the two objects is:

`\begin{gathered} F=(6.67428\cdot10^(-11)\cdot300\cdot1000)/(5^2) \\ F=(2.002284\cdot10^(-5))/(25) \\ F=8\cdot10^(-7)N \end{gathered}`
