उत्तर
Displacement of negative charge is responsible for generation of electric charge in an object.
Explanation:
When electrons (negative charges) move from one part of an object to another, they create an imbalance of charge. This movement of electrons causes the object to become electrically charged, with one side becoming negatively charged and the other positively charged. This displacement of negative charges is what generates electric charge in the object.
