Question

Which change will cause the gravitational force between a baseball and a soccer ball to increase? removing the outer layer of the baseball moving the balls farther apart wrapping the soccer ball in layers of duct tape using a baseball with a thinner leather

Answer 1

Answer:

Explanation:

We know that the gravitational force between two objects is given by :

where,

G is universal gravitational constant.

and are the masses of two objects.

r is the distance between them

i.e.

and

So, the correct options are :

(1) Moving the balls closer together. The distance decreases and force increases.

(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.

Answer 2
