Explain how electrically neutral objects can become electrically charged even though charge cannot be created or destroyed.
Nady [450]
Electrically neutral objects can become charged when they gain or lose electric charges. When an object is electrically neutral then the overall charge of the object is Zero. If a neutral object gains negative charges then it will become negatively charged, and if it looses the negative charges (electrons) then it becomes positively charged.
