In this video, we are going to focus on determining various factors for satellite.
00:04
So, for part a, we are going to determine the force of attraction between earth and the satellite.
00:10
And f is given as g into capital m into small m by r square, where g is the universal gravitational constant, m is the mass of earth and small m is the mass of the satellite and r is the distance between earth and the satellite.
00:23
And this is equal to 6 .67 into 10 to the power minus 11 into 35000 into 6 into 10 to the power 24 divided by 4 .2 into 10 to the power 7.
00:38
So, if we find the value, then we get the force of attraction is equal to 7940 .5 newton.
00:46
Now, moving on to next part, where we want to find the value of acceleration.
00:51
Now, centripetal force fc is given as mv square by r, which is equal to gm into small m by r square.
01:02
So, from here we get this, that is v square by r is equal to gm by capital r square.
01:09
And acceleration, centripetal acceleration is equal to f by m...
