When apositively charged sphere is brought near a metallic sphere, it is observed that a force of attraction exists between the two. If means:

A positive point charge q is brought near a neutral metal sphere.

A positive point charge q is brought near a neutral metal sphere.

A positive point charge Q is brought near a neutral metal cube.

A metal sphere is suspended from a nylon thread. Initially, the metal sphere is uncharged. When a positively charged glass rod is brought close to the metal sphere, the sphere is drawn towards the rod. But if the sphere touches the rod, it suddenly flies away from the rod. Explain, why the sphere is first attracted then repelled?
