Examine the scenario. Two neutral objects, a balloon and a sweater, are rubbed against each other. Which choice most accurately
Ne4ueva [31]

Electrons move from the sweater to the balloon. The sweater becomes positively charged, while the balloon becomes negatively charged.

Explanation:

  • Sweater is a conductive material, which means it readily gives away its electrons.
  • Consequently, when you rub a balloon on Sweater, this causes the electrons to move from the Sweater to the balloon's surface.
  • The rubbed part of the balloon now acquired  a negative charge. Objects made of rubber, such as the balloon, are basically electrical insulators, meaning that they resist electric charges flowing through them.
  • This is why only part of the balloon may have a negative charge (where the wool rubbed it) and the rest may remain neutral after electrostatic process.
