Jermaine and Lashonda each rub their dry hair with inflated balloons. While doing this, the other students notice that their hair is starting to stick straight out. Next, the teacher takes the balloons and places them right next to one another. However, the balloons will not stay next to each other, as they normally would. Instead, they spring apart in opposite directions.Explain what is causing these balloons to push each other away.

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

A	There must be a vent in the classroom blowing the two balloons apart.
B	They have each gained negative charge from the hair rubbing, and like charges repel each other.
C	They have each gained negative charge from the hair rubbing, and like charges attract each other
D	The rubber balloons are simply bouncing off each other the way a rubber ball bounces off the floor.

Explanation:

Detailed explanation-1: -What is causing these balloons to push each other away? As the balloons were rubbed on the hairs of Jermaine and Lashonda the balloons gained the static charge as both the balloons are made up of the same material and both were rubbed on the hairs the ballons gained the same type of charge.

Detailed explanation-2: -Because electrons are negatively charged, the balloon acquires a negative charge, while the hair, with its loss of negative charges, now has a net positive charge. So the balloon and hair have opposite charges, and opposite charges attract each other. That’s why the hair gets pulled toward the balloon (Figure 2).

Detailed explanation-3: -When you rub both balloons, both end up with negative charge. Similar charges repel so the balloons push away from each other. You can even use one balloon to push the other around!

Detailed explanation-4: -Rubbing the balloon onto your hair or onto the wool fabric adds electrons to the balloon and causes the balloon to become negatively charged. Like charges repel (the two balloons, once charged, will move away from each other) and opposite charges attract (the paper will be attracted to the charged balloons.)
