(03.04 MC) Which objects will likely have the greatest gravitational force
between them?
a) Two bowling balls that are near each other
b) Two bowling balls that are touching each other
c) Two soccer balls that are touching each other
d) Two soccer balls that are near each other

. Two tennis balls that are near each other

Explanation:

The formula for gravitational force (F) between two objects is

F = \dfrac{Gm_{1}m_{2}}{d^{2} }F=

d

2

Gm

1

m

2

where m₁ and m₂ are the masses of the two objects, d is the distance between their centres, and G is the gravitational constant.

Thus, two objects that are far from each other will have a smaller gravitational force. We can eliminate Options C and D.

If the objects are at the same distance, those with the smaller mass will have a smaller force.

The mass of a tennis ball is 57 g.

The mass of a soccer ball is 430 g.

Two tennis balls that are near each other will have a smaller gravitational attraction.
