U 11 Unu Imf. The masses of the earth and moonare 6 x 1024 kg and 7.4x1022 kg,respectively. The distance betweenthem is 3.84 x 105 km. Calculate thegravitational force of attractionbetween the two?Use G = 6.7 x 10-11 N m² kg-2Ans: 2 x 1020 N

Answer»

ans: 2*10^20N is the right answer

2*10*20N is right answer

Use Newton law of gravity F=Gm1m2/r^2m1=6×10^24kgm2=7.4×10^22kgr=3.84×10^8mG=6.7×10^-11Nm^2kg^-2
