SUMMARY
A positively charged rod induces a negative charge on a conducting sphere placed on an insulating surface through the method of induction. The conducting sphere experiences polarization due to the electric field created by the positively charged rod, resulting in a separation of charges within the sphere. The options of conduction and convection are ruled out, confirming that induction is the correct mechanism for this phenomenon. Therefore, the correct answer to the homework question is b) by means of induction.
