2. There may be only one or there may be more than one correct response to this question. You need only mark any one of the possible correct responses to be marked correct. A - Touch the top of the electroscope with your finger B - Remove your finger from the top of the electroscope C - Touch the top of the electroscope with a glass rod that was just previously rubbed by silk D - Touch the top of the electroscope with a rubber rod that was just previously rubbed with fur E - Remove the charged glass rod from the vicinity of the electroscope F - Remove the charged rubber rod from the vicinity of the electroscope G - Move the charged glass rod near the top of the electroscope H - Move the charged rubber rod near the top of the electroscope You are provided with an electroscope that may already have placed on it an unbalanced charge (that is the initial state of the electroscope might be overall positive, negative or neutral - you just don’t know!). You wish to make sure the electroscope has a negative charge. The steps you may take in doing this are provided above (A-H). Below is a set of steps done in a precise order that you can perform. Which of these sets of steps done in the order shown will result in the electroscope acquiring a negative charge through the process of conduction? There might be more than one correct set. A, H, B, F A, B, C, G A, D, F, B A, C, G, B A. B. D, F H, A, B, F G, A, B, E

A - Touch Top of the electroscope with your finger.

B - Then remove your finger from top of the electroscope.

D - Touch the top of the electroscope with a rubber rod that was just previously rubbed with furr.

F - Remove the charged rod from the vicinity of electroscope.

Correct Patteren is --- A B D F

As it is given that intially electroscope can be a +ve , -ve or neutral so to have to be sure that it is neutral we put place a finger and then charge get transfer to our body if electroscope has any charge and then we remove our finger . Now electroscope is electrically neutral . When we rub a rubber rod with a furr then rubbber rod gets -ve charge by gaining a electron from furr due to rubbing and then we place this rubber rod on the top of electroscope which transfer the -ve charge to the electroscope and which helps to get our electroscope -ve charge and then we remove our rubber rod from the vicinity of electroscope so our electroscope remains -ve charge. in this way we can have -ve charge on the electroscope.

I hope you like it. Thanku
