Physics: Static Electricity Quiz For 11th And 12th Grade

Rubber is an insulator as it does not allow electric charge to flow easily.

Conduction occurs when there is direct contact between materials that differ in their ability to give up or accept electrons.

The charging by induction process is where the charged particle is held near an uncharged conductive material that is grounded on a neutrally charged material.

The electric force between two charged objects depends on the magnitude of the charges and the distance between them.

If a positive charge and a negative charge interact, their forces act in the same direction, from the positive to the negative charge. As a result opposite charges attract each other: 

Coulomb is the SI unit of charge because one coulomb is that charge whose flow in one second results in one ampere current. 

Electromagnetism is not directly related to static electricity.

The electric field strength decreases as the distance between charged objects increases.

When an object gains protons, its positive charge increases.

Electric fields are areas around a charge so yes there can be an electric field at a point where there is no charge.
