Answer: towards the mass
Explanation: We know that the gravitational force is a long range force which is always attractive in nature.
Given that:
- mass
- mass
- mass
The masses are positioned on X-axis at the following points:
- Position of mass
- Position of mass
- Position of mass
Mathematically:
<em>Gravitational force on mass </em><em> due to mass </em>
<em> is given by </em>
...................(1)
- where:
= the radial distance between masses
&
=3
Similarly, g<em>ravitational force on mass </em><em> due to mass </em>
<em> is given by </em>
............................(2)
- where:
= the radial distance between masses
=3
Now, put the respective values in the above equations.
Again,
∵Mass is in the middle of the masses
&
therefore the forces
&
will attract them in radially opposite direction.
∴ towards the mass
