Question

the massea of the earth and moon are 6×10²⁴kg and 7.4×10²² kg , respectively. The distance between them is 3.84×5km. calculate the gravitational force of attraction between the two.
(G=6.7×10-¹¹)​

Answer 1

Answer:

2.017×10²⁰ N

Explanation:

use the formula

F=GM1×M2/R²

Answer 2

Answer:

Given, Earth mass=6×10^24 kg

.. Moon mass=7.4×10^22kg

Distance= 3.84×5 km OR 3.84×10^8

Gravity=6.7×10^-11

we, know

F=G.M.m/d^2

= 6.7×10^-11× 6.10^24×7.4×10^22/3.84×10^8×3.84×10^8

( 3.84×3.84 ) = 14.7456

= 6.7•6.10•7.4÷ 14.7456 × 10^35/10^ 16

=19.86064×10^19

=19.86064×10^20 N
