In the diagram above, a positive test charge is located between two charged spheres, A and B. Sphere A has a charge of +2q and is located 0.2 meter from the test charge. Sphere B has a charge of -2q and is located 0.1 meter from the test charge. If the magnitude of the force on the test charge due to sphere A is F, what is the magnitude of the force on the test charge due to
sphere B?
2F
2F
4F
4F

The diagram above shows two negatively charged balloons
suspended from nonconducting strings being held by a student. What occurs as the student brings the balloons closer to each other without allowing them to touch?
The magnitude of the electrostatic force between the balloons increases, and they attract each other.
The magnitude of the electrostatic force between the balloons decreases, and they repel each other.
The magnitude of the electrostatic force between the balloons increases, and they repel each other.
The magnitude of the electrostatic force between the balloons decreases, and they attract each other.
An electrostatic force of magnitude F exists between two metal spheres having identical charge q. The distance between their centers is r. Which combination of changes would produce no change in the electrostatic force between the spheres?
