The masses of the earth and moon are 6×10²⁴ kg and 7.4×10²² kg, respectively.The distance between them is 3.84×10(raised to)5 km. Calculate the gravitational force between the two? Use G=6.7×10(raised to) -11 Nm²kg(raised to)-2. please guys give me this solution for this derivative.

Answer:
20.2 × 10¹⁹ N
Explanation:
Given :
Mass of earth = 6 × 10²⁴ kg
Mass of moon = 7.4 × 10²² kg
Distance between them = 3.84 × 10⁵ km = 3.84 × 10⁸ m
We have value of G = 6.7 × 10⁻¹¹ N m² kg⁻²
We have to find force :
We have :
F = G m₁ m₂ / r²
F = ( 6.7 × 10⁻¹¹ ) ( 6 × 10²⁴ ) ( 7.4 × 10²² ) / ( 3.84 × 10⁸ )² N
F = 20.2 × 10¹⁹ N
Hence force exerted by the earth on the moon is 20.2 × 10¹⁹ N.
