Explain using an example how to charge an object positively using only a negatively charged object.

Answer 1

You can charge an object positively using a negatively charged object by induction. Bring the negatively charged object close to but not touching the neutral object. A separation of charge will occur in the neutral object as the electrons repel to the far side. Provide a ground and the electrons will repel further into the ground. Remove ground and then the negatively charged object. The neutral object is now positive because it has lost electrons to the ground.
