Two spherical balls of mass 10kg each are placed 10cm apart.find the gravitational force of attraction between them.

F_{gravitational}=Gm1m2/r²

G=6.67300 × 10^-11 m³ kg^-1 s^-2, m1=m2=10kg,r=0.1m

F_{gravitational}=(6.67300 × 10^-11 m³ kg^-1 s^-2x10kgx10kg)/(0.1m)²

              =6.6730x10^-7

Mass of each ball =m1=m2=10kgDistance between them =d=10cm=0.1mGravitational force of attraction =G=m1,m2/d2 F=(6.670*10-11)*10*10/(0.1)2 =6.67*10-11*102/6.01 =6.67*10-11*102/102 =6.67*10-11*102*102 =6.67*10-11*104 =
