Question
What method of static charging is shown in this picture:
- Polarization
- Friction
- Induction
- Conduction
Hint:
Friction refers to the method of static charging exhibited by sliding or rolling an object over another.
The correct answer is: Friction
The static charge generated when an object is sliding over another is called friction.
- The method of static charging exhibited by sliding or rolling an object over another is called friction.
- Friction is generated when an object is rubbed over another.
- The force created when an object is sliding over another is called frictional force.
