Solution:

• Static electricity is the imbalance of electric charges within or on the surface of a material.
• Static electricity is a familiar electric phenomenon in which charged particles are transferred from one body to another.
• For example, if two objects are rubbed together, especially if the objects are insulators and the surrounding air is dry, the objects acquire equal and opposite charges and an attractive force develops between them.
• The object that loses electrons becomes positively charged, and the other becomes negatively charged. The force is simply the attraction between charges of opposite sign.
