If a neutral metal object has been charged by friction to a charge of one pC, what has happened to it electrically? A) 6.25 × 10⁶ electrons have been added to it B) 6.25 × 10⁶ protons have been added to it C) 6.25 × 10⁶ electrons have been removed from it D) 6.25 × 10⁶ protons have been removed from it E) 6.25 × 10⁶ electrons and protons have been added to it

When a neutral object is rubbed against another material, some of its electrons may transfer to the other material, leaving the neutral object with a positive charge. In this case, the object has a charge of one pC, which corresponds to a deficit of 6.25x10^10 electrons. Therefore, choice C is the correct answer as it states that electrons have been removed from the object.
