Solution 2.6

Use the theory of gravitation equation

F=d 2Gm1m2

where,

G=6.6710−11 kg-1m3s-2

In this case

m1 is the mass of the earth and m2 is the mass of the satellite.

d is the distance of the satellite from the centre of the earth and thus is the sum of the radius of the earth and its height above the earth.

Thus

m1= 5.981024 kg


m2=300 kg

The radius of the earth is

6.37106 m

and the height of the satellite above the earth in SI units is 7106 m

which gives

d=13.37106 m

Inserting all these quantities in the gravitation equation

F=13.3710626.6710−115.981024300=178.761012119.661015=0.669103 =669 N
