The negative charge on the balloons is due to an excess of electrons in the material they are made of. When the balloons are rubbed against certain materials, such as hair or wool, they gain electrons and become negatively charged.
The negative charge on the balloons creates an electrostatic force that repels the electrons in the strings. This repulsive force causes the strings to stretch and creates tension in the strings.
The tension in the strings is affected by several factors, including the distance between the balloons, the amount of charge on the balloons, and the length and thickness of the strings. The material and weight of the balloons can also impact the tension.
The balloons repel each other because they both have a negative charge. Like charges repel each other, so the balloons will push away from each other due to the electrostatic force between their negative charges.
The tension in the strings can be calculated using Coulomb's law, which states that the force between two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. The tension can also be measured using a spring scale or by observing the amount of stretch in the strings.
