In an experiment, an uncharged conductor sphere is hung on a nylon (insulator) thread. When a positively charged glass rod is brought close to the sphere, the sphere is attracted to the rod. But, once the sphere touches the rod, it suddenly jumps from the rod. Explain why the sphere move away from the rod

Electric Charges and Fields

One of the fundamental properties is the electromagnetic property. Charge cannot be destroyed by any process and this contributes formally to the law of charge conservation.
