Question

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 1

Answer:

Use formula  F=GmM/$R^{2}$

Explanation

where M= mass of earth

m= mass of moon

R= distance b/w them

after solving with the given formula you will get answer = 2.01741  $10^{48}$

Answer 2

The mass of the earth MS equal to 6×10 power 24 KG the mass of the moon M is equal to 7.4×10 power 22 KG the distance between the earth and the moon D is equals to 3.84×10 power 5 km equals to 3.8×10 power 5 in 2000 meter equals to 3.84×10 power 8 m G is equal to 6.7×10 power -11 and I am Square KG -2 from the equation in the force exerted by them earth on the moon is SS equal to G into M into M divided by D Square equal to 6.7×10 power -11 NM Square KG square into 6×10 power 24 KG into 7.4×10 power 22 KG divided by 3.84×10 power 8 m² equals to 2.02×10 power 20 N is the force exerted by the earth on the moon is 2.02×10 power 20 N
