The opposite of an ordinary apple in terms of electric charge would be an "anti-apple". Similar to an ordinary apple, the anti-apple would have a positive charge.

An anti-apple, in the context of electric charge, is a hypothetical fruit that possesses an opposite charge to an ordinary apple. While an ordinary apple may be neutrally charged or have a slight negative charge, an anti-apple would have a positive charge. This term is used to illustrate the concept of opposite charges in electromagnetism and does not indicate the existence of an actual fruit called an anti-apple in real life.
