Hello everyone, so there are three uniform spheres, okay? so we are considered a let's suppose the first sphere and this is your second sphere, now third sphere, okay? each having a mass, that is a mass, is a small m, that is also a small m, that is also a small and a radius is the same smaller, smaller and a smaller.
00:20
Are kept in such a way each other touch two, okay.
00:24
So each touch the two other, okay? so that means just like that, this is the first.
00:30
That is the second and this is a third okay this is a possibility so you can see that that is a triangle will be formed the magnitude of a gravitational force on any one okay any other so we can just calculate a guys that is a due to due to sphere due to any sphere f1 okay so we are considered these are the g m squared and divided by this is the this is the radius and that is the radius and that is also radius.
01:01
So this is the 2r distance.
01:04
So we can write here that is a 2r and a whole square.
01:07
So it is equivalent to a gm square and divided by 4r square.
01:13
Now we are talking about a similarly for a second sphere.
01:16
Okay.
01:17
Due to the sphere second, so we are considered that is the f2 is equivalent to a gm square and divided by same 4r square students...
