Electricity

Question 1 of 19

1

What is Charging by Friction

Select one of the following:

  • Takes place when contact is made between a neutral object and a charged object

  • when static charges build up as different materials rub together

  • when a charged object is close to a neutral object, the electric field of the charged object produces an attractive force on the neutral object
