    I've got some physics questions due on Wednesday. These are theory questions about Electric Forces and Fields, all the basic stuff; nothing complicated.
    I searched for it in Google and didn't really find the answer.
    If you have 10-15 minutes of free time i'd really appreciate if u could help me on Skype or just here on BHW.

    1) A positive metal object touches a neutral metal sphere. Charging by Induction.
    Final charge of object Negative.
    Final charge of sphere Positive.

    2) An object is brought near a charged electroscope and the leaves come closer together. What is happening to the charges of the leaves? Attaraction.

    3) A positive object is brought near a neutral electroscope, and while it is near, the scope is grounded.
    Final charge of scope No charge because earthing takes place so charge flows to the ground.
    Charging by Induction.
