Andrew E hanged a neutral metal sphere using a nylon thread. Andrew observed that when a glass rod that is positively charged is placed close to the sphere, attraction between the sphere and the rod occurs. However, after this, when the sphere touched the rod, both suddenly repelled each other. Why is this?
