When an object becomes charged by friction, it is due to the transfer of electrons between two different materials. This process is also known as triboelectric charging.

Here's a step-by-step explanation:

1. When two different materials come into contact, such as the sticky tape and the student's hand, there is a tendency for electrons to move from one material to another. This is due to the differences in the materials' affinity for electrons, or their electronegativity.

2. In the case of the sticky tape, when it is pulled from the roll, the friction between the tape and the roll causes electrons to be transferred. The direction of the electron transfer depends on the materials involved, but let's assume in this case that electrons are transferred from the tape to the roll.

3. As a result, the roll becomes negatively charged (since it has gained electrons), and the end of the tape becomes positively charged (since it has lost electrons).

4. This charge remains on the objects until it is discharged, such as by touching another object and transferring the excess electrons.

So, in summary, an object becomes charged by friction when electrons are transferred due to the friction between two different materials.

A student holds a roll of sticky tape and pulls the end down. This causes both the roll and the end of the tape to become electrically charged by friction. (a) Explain how an object becomes charged by friction
