  • Electrostatic force is a non-contact force between two charged objects.
  • It is similar to gravity but depends on electric charge instead of mass.
  • Objects with opposite charges attract each other, known as electrostatic attraction.
  • Objects with like charges repel each other, known as electrostatic repulsion.
  • Static charge occurs when objects gain or lose electrons.
  • A charged object can cause electrostatic forces, such as a charged rod bending water from a tap.
  • Water molecules have positive and negative parts, allowing them to be attracted to charged objects.
  • Rubbing a balloon against hair transfers electrons, causing static charge and electrostatic attraction.
  • The balloon becomes negatively charged, and hair becomes positively charged, leading to attraction.
  • This concept is often tested in exams, demonstrating static charge and electrostatic forces.
