Question

A negatively charged object is kept near iron sphere. What can be observed in its “m” side and “n” side?

• A. Side "m" is positively charged
• B. Side "m" is negatively charged
• C. Side "n" is positively charged
• D. Both "m" and "n" are positively charged

Answer 1

The correct option is A Side "m" is positively charged

Every conducting object (like iron sphere) 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 "m" will move towards the side "n" due to repulsion.
Therefore, the side "m" will be positively charged and side "n" will be negatively charged to make the iron sphere overall neutral.
