Ok, so we know that time period square can be equal to 4 pi square times r to the power 3 over gm.
00:07
So if we do some comparison here, we can say that the time period for the asteroid square over the time period for the earth square can be equal to such equation here.
00:22
And then if we do some arrangement here, this is actually equal to 4 pi square times r8 to the power 3 over gm times gm over 4 pi square times re to the power 3.
00:31
R .a here is the orbital radius for the asteroid, which is the semi -major axis of its orbits while looking for to determine.
00:42
And r .e here is the radius, i'm sorry not radius, the orbital radius of the earth.
00:49
So now, as you can tell, 4 pi square can be canceled out, and gm can be cancel out.
00:53
It will give us t .a.
00:55
Over t .e.
00:56
To the power 2 is equal r .a.
00:57
Over r .e...
