To determine whether an object has a positive charge, a negative charge, or is electrically neutral, the student can follow these procedures and interpret the expected results. The correct statements from the options provided are:
C) Bring a pith ball that has a negative charge near the object. If the ball is attracted, the object has a positive charge.
F) Bring a pith ball that has a positive charge near the object. If the ball is attracted, the object has a negative charge.
Explanation:
- Like charges repel, and opposite charges attract. Therefore:
- If a negatively charged pith ball is attracted to the object, the object must have a positive charge.
- Conversely, if a positively charged pith ball is attracted to the object, the object must have a negative charge.
The other statements (A, B, D, E) are incorrect as they either misinterpret the nature of electric charge interactions or incorrectly predict the expected results.
