So the question is we have to find the force of attraction between a body of unit mass and the moon.
00:07
So for this given, we'll say mass of the body that is, let's say small m is equal to 1 kg that is the body of unit mass.
00:18
We'll say capital m as the mass of the moon, which is given to us as 7 .4 into 10 rest to 22 kilograms.
00:27
We have the radius of moon also, which is equal to 1 .70.
00:31
24 into 10 rest to 6 meters.
00:37
And we have to find the force of attraction between these two.
00:41
So for solving these types of sums, we have to use the standard formula that is f is equal to g m .m upon r square.
00:52
Now here the g is the universal gravitational constant which you have to buy hard the value because sometimes it is not given in the question.
01:00
So, that value is 6 .67 into 10 rest to minus 11 into capital m is 7 .4 into 10 rest to 22 into small m is 1...
