Astream of water will bend toward a balloon that has been rubbed on a sweater to generate static charge. which property of water is responsible for this behavior ?

The correct answer is the polarity of the water molecule.

Explanation:

When a balloon is rubbed on a sweater it acquires a charge on its surface that produces a static charge on it. Thus, when a stream of water is targeted over the balloon, the bending of the stream of water takes place towards the balloon that exhibits static charge over it, as water possesses a dipole moment of 1.85. The production of dipole moment takes place when there is a separation of charge between the terminals of the molecule.

sorry, but you do not have posted the diagram.
