Question

5. Rub the yellow balloon on the sweater until you get all of the blue negative charges on the balloon. When you rub two things together and there is a transfer of negative charge, this charge distribution is called friction. Now, drag the balloon in between the wall and the sweater. Then release the balloon to see what happens. Explain what happened and why.
well the balloon gravitate to the sweater and not the wall

Answer 1

When the yellow balloon is rubbed against the sweater, it gains negative charges from the sweater due to friction. This means that the balloon becomes negatively charged, while the sweater becomes positively charged as it loses some negative charges.

When the negatively charged balloon is dragged between the wall and the sweater, it will be attracted to the positively charged wall. This is because opposite charges attract each other.

However, when the balloon is released, it does not stay attracted to the wall and instead gravitates towards the sweater. This is because the sweater has a stronger positive charge compared to the wall, resulting in a stronger attractive force between the balloon and the sweater.

So, the balloon moves towards the sweater because it is attracted to the stronger positive charge on the sweater compared to the wall.
