Sonia was experimenting with electric charges. She tied two inflated balloons together, held them next to each other, and rubbed both with a piece of wool. What did Sonia observe, and why?

Here when we rub the balloon with the woolen cloth then due to friction between the cloth and balloon electrons from balloon will transfer to woolen cloth.

Due to transfer of electron the balloon will get positive charge which is given by

[tex]Q = Ne[/tex]

so here since both balloons are rubbed against woolen cloth so both balloon will get some positive charge

now we know by the property of charge that two similar charges will always repel each other so here two balloons will repel each other after they rubbed against woolen cloth.

Sonia observed that both ballons repulse each other.

The repulsion in balloons was caused by the amount of the same positive charge that remained at the surface of the balloons.

Repulsion

Repulsion between two objects can be defined as a tension that pushes both objects away from each other.

The experiment says that two inflated balloons are held next to each other and rubbed by a piece of wool.

In this case, when the balloons are rubbed by a woolen piece then there is friction occurs between the balloon and woolen piece. This friction transfers the electrons of the balloon to the woolen piece.

Hence, there is only positive charge remains on the surface of the balloon.

Both the balloons are rubbed by the woolen piece, hence both the balloons have positive charge on their surface.

The charge has a property that if two similar charges will come into contact with each other, they will repel each other. So when sonia rubbed the balloons with a piece of wool, both the balloons repels each other because of the same positive charge at their surface.

Hence, Sonia observed that both ballons repulse each other.
