O a. at least one of them to be charged O b. both of them to be charged, oppositely O C. both of them to be charged the same way O d. both bars having equal and opposite charges O e. both bars having equal and same polarity charges QUESTION 10 How does the moisture in the air affect the experiment? a. Increases the reaction forces b. Decreases the reaction forces C. Does not affect any thing d. Makes transfer of charge between the rod and fabric easier e. Makes transfer of charge between the rod and fabric harder

Explanation / Answer

9) even atleast one is charged, the opposite charge on the other can be induced, thus they can attract

10) d, make the transfer of charge easier
