shepuryov [24]

True

Explanation:

The statement that when the distance between the balls decreases, the size of arrow increases because it shows the gravitational pull between the two balls which increases is true.

According to Newton's law of universal gravitation:

"The gravitational force of attraction between two bodies is directly proportional to the product of their masses and inversely proportional to the square of their separation".

Mathematically, the law is written as:

F = $\frac{G m_{1} m_{2} }{r^{2} }$

F is the gravitational force

G is the universal gravitational constant

m is the mass of the body

r is the distances between them.

We see that the less the distance between the two bodies the more the gravitational force they have.
