If the distance between two electric charges is halved, the value of the electric force between them will become quadruple. This is because the force between two charges increases as the distance between them decreases. Halving the distance results in ...

The force between two electric charges is related to Coulomb’s law. This law describes how the electric force between two charged objects depends on the amount of charge on each object and the distance between them. Coulomb’s law is fundamental ...
The entire charge of a charged conductor remains on its outer surface. This occurs because like charges repel each other and move as far apart as possible, resulting in the charges spreading out evenly on the outer surface of the ...
When a glass rod is rubbed with silk, the rod becomes positively charged. This occurs because electrons are transferred from the glass rod to the silk, leaving the rod with a deficiency of electrons and thus a positive charge.
Light travels slower in glass than in air because the refractive index of air is less than the refractive index of glass. The higher refractive index of glass indicates that light interacts more with the glass material, causing it to ...
