Answer #1

When we rub the balloon from our hairs then there will be charge arrived at the surface of balloon. as balloon is insulator so the charge does not move and remains on the surface. And when we take it near the wall surface that is also an insulator there are a lot of small charges at surface of wall they get attracted by charge on balloon. so the balloon stucked there.

The principle used here is charging by friction between hair and balloon. and also free charge attracted by other charges.

thanks.

    Rub a comb through your hair and use it to lift pieces of paper. It may help to tear the pieces of paper rather than cut them neatly. Repeat the exercise in your bathroom after you have had a long shower and the air in the bathroom is moist. Is it easier to get electrostatic effects in dry or moist air? Why would torn paper be more attractive to the comb than cut paper? Explain your observations.
