Question

A student combed his hair. Then he observed what happened to the water when he put the comb near the faucet as shown. Why did the water's path change?

due to conduction, the charged comb repelled the neutrally charged water
due to induction, the charged comb repelled the neutrally charged water
due to conduction, the charged comb attracted the neutrally charged water
due to induction, the charged comb attracted the neutrally charged water

The correct explanation for why the water's path changed when the student put the charged comb near the faucet is:

**due to induction, the charged comb attracted the neutrally charged water.**

When the charged comb is brought close to the stream of water, it induces a separation of charges within the water molecules. The molecules are polar, meaning they have a positive end and a negative end. The charged comb will attract the opposite charges in the water, leading to the deflection of the water stream toward the comb.
