Questions: 1. Note that in the previous video, the balloons were charged and then allowed to move freely, so the electric force caused the Saved balloons to move away from each other. In this video, however, the spheres are fixed in place. How do you know they are exerting a force on each other after they are charged? What evidence do you see from the video?

Solution Steps

In the scenario described, two spheres are charged and fixed in place. When objects are charged, they exert electric forces on each other due to the presence of electric charges. The nature of these forces depends on the type of charges present on the objects.

To determine if the spheres are exerting a force on each other, we need to look for evidence of interaction between them. In the video, if the spheres are charged, they will either attract or repel each other depending on whether they have opposite or like charges, respectively.

Since the spheres are fixed in place, direct movement is not possible. However, evidence of force can be observed through other means, such as:

• The tension or deformation in the supporting structures or materials holding the spheres in place.
• Any visible deflection or bending of the supports, indicating that a force is being exerted.
