Question

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. (Take G=6.7 * 10-11 N m² kg 2)​

Answer 1

Explanation:

Answer:-

Given:

✍️Mass of earth = 6 × 10²⁴ kg

Mass of moon = 7.4 × 10²² kg

Distance between them = 3.84105 km = 3.84105 × 10³ 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 ) / (  3.84105 × 10³ )² N

• F = 2 × 10³⁰ N

Hence force exerted by the earth on the moon is 2 × 10³⁰ N.

hope this helps you ☺️
