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
The 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. Which result should he expect, and why?(1 point)
The result Bobby should expect is that the balloons will repel each other when he touches them with a metal rod and allow them to settle after rubbing them 10 times with animal fur.
This is because when Bobby rubs the balloons with animal fur, it transfers electrons from the fur to the balloons, creating a buildup of negative charge on the balloons. Since both balloons have the same charge, they will repel each other, causing them to hang a small distance apart.
When Bobby touches the balloons with a metal rod, it allows for the transfer of charge between the balloons, equalizing their charge. This causes the balloons to no longer repel each other and instead settle back to their original position.
However, when Bobby rubs the balloons again with animal fur for 10 times, it creates another buildup of negative charge on the balloons, causing them to repel each other once more.
