A4-kg ball is 2 cm away from one 1-kg ball and 6 cm away from another 1-kg ball. use the relationships among the balls to describe two factors that affect gravity. also explain why the balls do not move toward each other unless acted upon by another force.

Force of gravitation between two balls is given by the formula

here we know that

= mass of ball 1

= mass of ball 2

= distance between two balls

So here the two factors that will affect the force of gravitation is

1. Distance between two balls

2. mass of two balls

Here balls do not move due to gravitation attraction force because here the force of gravitation is very small as it is compared with other forces like frictional force between balls and ground.

So this weak gravitational force is balanced by frictional force on balls

SO all balls remains at rest
