Example 10.1 The mass of the earth is
6 x 1024 kg and that of the moon is
7.4 x 1022 kg. If the distance between
the earth and the moon is 3.84x105 km,
calculate the force exerted by the earth
on the moon. G = 6.7 x 10-11 N m² kg 2.

Answer:
20.1*10^19 Nm^2/kg^2
Step-by-step explanation:
Given that,
Mass of the Earth m1=6*10^24 KG
Mass of the moon m2=7.4*10^22 KG
Distance between the Earth and the Moon d=3.84*10^5 KM=3.84*10^8 M
gravitational constant=6.7*10^-11 nm^2/kg^2
now by using newtons law of motion
f=G*m1*m2/r^2
f=6.7*10^-11*6*10^24*7.4*10^22/(3.84*10^8)^2
f=20.069*10^19 N
f=20.1*10^19 N
