What happens when two objects are charged by contact?
What happens when two objects are charged by contact? When two neutral objects come into contact–especially in a dry environment–electrons can be knocked loose from one object and picked up by the other. The object that gains electrons becomes negatively charged, while the object that loses electrons becomes positively charged. What is an example of […]
