Question

The masses of the earth and moon are 6×10rase to 24 kg and 7.4×10rase to 22kg respectively. The distance between them is 3.84×10 rase to 5. Calculate the gravitational force of attraction between the two?

Answer 1

hope this helps you.
marking the answer brainleast would be appreciated ^_^

Answer 2

Mass of earthM=6×10^24kg
Mass of moon m=7.4×10^22kg
Distance d=3.8×10^5km
d=3.8×10^5×1000
d=3.84×10^8
G=6.7×10^-11
By using gravitational law;F=G×M×m/d^2
F=2.01×10^20 is answer
