Question

field lines point out from all sides of an object. some of the lines point into a second object nearby. which statement best describes the objects?
a. both objects are permanent magnets.
b. both objects are electromagnets.
c. the first object is positively charged, and the second object is negatively charged.
d. the first object is negatively charged, and the second object is positively charged.

Explanation:

• For electric field lines: They start from positive charges and end at negative charges.
• In the given situation, field lines point out from the first object (so it is positively charged) and into the second object (so it is negatively charged).
• For magnets (permanent or electromagnets), magnetic field lines form closed loops (from north - pole to south - pole outside the magnet and south - pole to north - pole inside the magnet), which is different from the described situation.

Answer:

C. The first object is positively charged, and the second object is negatively charged.
