Hello.
00:01
So it is given to us in the question that the speed of the satellite a is 10 ,000 meter per second.
00:08
It is also given to us that the mass of the satellite b equals twice the mass of the satellite b is taken as mb and mass of satellite b is taken as ma.
00:20
Also, the radius of the orbit of satellite b is equal to twice the radius of the orbit of satellite a.
00:30
Now the radius of the orbit of satellite a is taken as ra and the radius of the orbit of satellite b is taken as rb.
00:40
Now we know that the centripetal force acting on the satellite a will be equal to ma multiplied by va square divided by ra.
00:55
Similarly, the centipital force acting on satellite b would be equal to mb multiplied by vb squared by rb.
01:11
Now substituting for mb and rb in this equation, we get fbc equals 2ma multiplied by vb square divided by 2 .2 .2 .2 .2.
01:27
R a, which is equal to m .a multiplied by vb squared by ra.
01:39
Now fac divided by fbc gives m .a.
01:51
Va .2a.
01:53
Divided by ra.
02:00
M -a -v -b -square.
02:04
Therefore, f -a -c divided by f -b -c equals v -a -square divided by v -b -b -square...
