Two spherical balls of mass 10 kg each are placed with their centers 10 cm apart. Find the gravitationl force of attractdion between them.

The Gravitational force of attraction between two bodies of masses m1 and m2separated by a distance of R is given by;


G = Gravitational constant;


The figure below illustrates the question well;



According to our question;


m1 = ;


m2 = ;


R = 10 cm = = 0.1 m (1 m = 100 cm).


F =


⇒ F =


⇒ F =


⇒ F =


Hence force between two spherical balls is 6.67 x 10-7 N
