Question

PLEASE HELP!!!!!

Answer 1

Answer: The electroscope had a negative charge before the experiment started.  When the negatively charged rod comes near the electroscope more electrons are repelled down to the metal pieces and the metal pieces move farther away from each other.

 Step-by-step explanation: First of all, how we know the answer is not A or B is because unlike charges attract each other which means the metal pieces would not spread out. Now that we narrowed it down to C and D we can find the answer, In answer choice D it states that the negatively charged rod attracted the electrons from the electroscope, if that happened then something would happen to the rod, not the electroscope. In answer choice C it says that the rod repels the electrons downward on to the metal pieces, which would cause the metal pieces to spread out since they are both negative. Sorry, I'm not the best with explaining, I hope you understand.
