Physics SP11 - Static electricitywith complete verified
solutions
11.1P Explain how an insulator can be charged by
friction, through the transfer of electrons - answer
When insulating materials rub together, negatively
charged electrons are transferred from one
material to another.
The electrons, as the materials are insulators, are
not free to move - so the build-up of charge is
static electricity.
11.2P Explain how the material gaining electrons
becomes negatively charged and the material
losing electrons is left with an equal positive
charge - answer The material gaining electrons
ends up with a negative static charge.
The material losing electrons ends up with a equal
positive static charge.
11.3P - answer Like charges repel and unlike
charges attract.
