Bobby hangs two inflated balloons from 2-meter strings so that they touch. He then holds the balloons apart and rubs each balloon 5 times with animal fur. He then releases the balloons. The balloons now hang a small distance apart from one another:%0D%0A%0D%0A%0D%0A%0D%0AThe next step in Bobby's procedure is to touch the balloons with a metal rod and allow them to settle, and then to rub them 10 times with animal fur.

The correct response is: The balloons will hang at a smaller elevation, because more thoroughly rubbing them will more completely remove their charges, reducing the electrical repulsion between them.
