select the correct answer. what is the force that can cause two pieces of iron to attract each other? a. gravitational force b. magnetic force c. elastic force d. electrostatic force
Answer
Answer:
B. magnetic force
Explanation:
Step1: Analyze gravitational force
Gravitational force is between masses, weak for small - scale objects like two pieces of iron, not main cause of their attraction.
Step2: Analyze magnetic force
Iron is a ferromagnetic material. Magnetic force can attract ferromagnetic materials like iron, so it can cause two pieces of iron to attract.
Step3: Analyze elastic force
Elastic force occurs when an object is deformed and tries to return to its original shape, not related to iron - to - iron attraction.
Step4: Analyze electrostatic force
Electrostatic force is between charged objects, not the main force for uncharged iron pieces to attract each other.
