Question 1
Question
What is Charging by Friction
Answer
-
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
