The magnitude of the gravitational force exerted by ball A on ball B is equal to 36.31 × 10⁻¹¹ N.
<h3>What is gravitational force?</h3>
Newton’s law of gravitation can be defined as every particle of matter in the universe attracting every other particle with mass with a certain force. The magnitude of gravitational force has a direct relationship with their masses.
Therefore, the gravitational force between two bodies can be written as:

Where G denotes the universal gravitational constant.
Given, the mass of the Ball A = Ball B = 7 Kg
The separation between the two balls, r = 3 m
The magnitude of the gravitational force applied by ball A on ball B can be determined as:

F = 36.31 × 10⁻¹¹ N
Therefore, the gravitational force is equal to 36.31 × 10⁻¹¹ N.
