Question

When a negatively charged object is brought near an iron rod what can be inferred about its side A?

• A. Side A is neutral
  
• B. Side A is positively charged
  
• C. Side A is negatively charged
  
• D. Side A cannot be determined

Answer 1

The correct option is B Side A is positively charged


Every conducting object (like iron rod) initially can be assumed to have no net charge (neutral). Later, as a negative charge is brought near to it, all the electrons from side A will move towards the right due to repulsion, so the side A will be positively charged to make the iron rod overall neutral.
