Hello friends, in this question it is given that there is a satellite which is orbiting around the earth at an altitude means height of 650 km.
00:12
We can write this as 650 multiplied by 10 to the power 3 meter.
00:18
Then it is given that what should be the orbital speed of this satellite so that the satellite can stay in this orbit at this.
00:30
Altitude.
00:31
Then the mass of earth is given as 5 .9722 into 10 to the power 24 kilograms and radius of earth is given as 6 ,371 kilometer and this can be written as 6 ,371 multiplied by 10 to the power 3 meter.
01:00
So we want to calculate what should be the orbital speed of this satellite.
01:07
So we can understand what is the situation here.
01:10
So let us suppose this is our earth.
01:14
So initially the satellite is at, let us suppose at this position.
01:19
So from the surface, the height of satellite is edge and this is radius of satellite.
01:24
So, we want the orbital speed of this satellite.
01:31
And orbital speed is given by v is equal to square root of g, capital m divided by r.
01:37
Here g is universal gravitational constant...
