The three options are 1,3 and 5 Moving the balls closer together. The distance decreases and forces increase.
<h3>What is the gravitational force?</h3>The gravitational force ia s type of force has the ability attracts any two objects with mass. Gravitational force tries to pull two masses towards each other.
The value of the gravitational force is given by;
It is observed that the gravitational force is directly propotional to the product of mass and inversly propotional to the square of the distance between them.
So, the correct options are :
(1) Moving the balls closer together. The distance decreases and forces increase.
(3) Wrapping the soccer ball in layers of duct tape will also increase force because the mass will increase.
(5) Similarly, putting the baseball in a plastic case will increase mass, and hence force increases.
Hence the three options are 1,3 and 5.
