To charge an object by induction. : Rub a comb or a balloon on your hair. As shown in the picture 8.4 on page 54 of your textbook, take the comb near a thin trickle of water from a tap what happes. Now draw the comb away from the trcikle and observe what happens. : Mark your observation with a tick. : When the charged comb is brought close to the flowing water, water gets attracted/repelled/remains as it was. : when the charged comb is taken away from the flowing water, it gets attracted.repelled/remains as it was initially.
