Final answer:
The force between two charged objects can be calculated using Coulomb's Law. In this case, the charges of the balloons are both -0.0025 C and the distance between them is 8 m. Since the charges are the same, they will repel each other according to the law of electrical charges, resulting in a repulsive force of 0.000486 N.
Step-by-step explanation:
The force between two charged objects can be calculated using Coulomb's Law. The equation for the force between two point charges is:
F = k * (q1 * q2) / r^2
Where F is the force, k is the Coulomb's constant (approximately 9 x 10^9 Nm^2/C^2), q1 and q2 are the charges of the objects, and r is the distance between them.
In this case, the charges of the balloons are both -0.0025 C and the distance between them is 8 m. Since the charges are the same, they will repel each other according to the law of electrical charges. Therefore, the force between the balloons is repulsive.
The force between the balloons can be calculated as follows:
F = (9 x 10^9 Nm^2/C^2) * (-0.0025 C * -0.0025 C) / (8 m)^2
F = 0.000486 N
