FLASHCARD QUESTION

Front

In which direction will a positively charged particle move when placed next to a negatively charged object?

Back

The positively charged particle will move toward the negatively charged object, which exerts an attractive force as a result of its electric field.

How can electric fields be used to develop a levitation device?

Back

Electric fields can cause objects to attract and repel one another. Repulsive electric forces may be used to help levitate a charged object.
