Question

show that the weight of an object on the moon is 1/6 of the earth given that Me=6*10^24 kg ,Mm=7.4 *10^22 ,Re=6.4*10^6m
plz tell
​

Answer 1

Explanation:

Given that,

Mass of the Earth m1=6×1024kg

Mass of the Moon m2=7.4×1022kg

Distance between the Earth and the Moon d=3.84×105km=3.84×108m

 Gravitational Constant G=6.7×10−11Nm2/kg2

Now, by using Newton’s law of gravitation

  F=r2Gm1m2

 F=(3.84×108)26.7×10−11×6×1024×7.4×1022

 F=14.8225×1016297.48×1035

 F=20.069×1019

 F=20.1×1019N

Hence, the gravitational force of attraction is
