Question

The masses of the earth and moon
are 6 x 1024 kg and 7.4x1022 kg,
respectively. The distance between
them is 3.84 x 105 km. Calculate the
gravitational force of attraction
between the two?
Use G = 6.7 x 10-11 N m² kg?​

Answer 1

Answer:

Given:-

Mass of earth = 6 x 10kg

Mass of moon = 7.4 x 10²² kg

Distance between them = 3.84 x 105 km =

3.84 x 10^8m

We have value of G = 6.7 x 10^-11 Nm² kg^-2

We have to find force:-

We have:

F = G m1 m2/r²

F=(6.7 × 10^-11) (6 x 10^24) (7.4 × 10^22)/(3.84 x 10^8)² N

F = 20.2x 10^19N

Hence force exerted by the earth on the moon is 20.2 x 10^19 N.

Answer 2

Answer:

F=Gm1m2/r²

F=6.7*10-¹¹*6*10²⁴*7.4*10²²/(3.84*10⁵)²

F=297.48*10³⁶/14.7456*10¹⁰

F=20.17*10²⁶

F=2.017*10²⁷
