A neural (uncharged) metal ball is suspended using a non-magnetic string. A positively charged insulating rod is placed near the ball which is observed to be attracted to the rod. This is because

A positively charged glass rod is brought near an uncharged pith ball penduium. What happens to the pith ball ?

In normal cases thin stream of water bends toward a negatively charged rod. When a positively charged rod is placed near the stream, it will bend in the

You are given a negatively charged pith ball, hanging from a string, and a non-conducting rod. As you bring the rod near the ball you find that the ball is attracted towards the rod. From this experiment it is not possible for you to determine whether the rod is charged positively or neutral. Why not? What additional experiment would you propose to conduct to decide between these two possibilities?

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

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

A positively charged glass rod attracts a suspended pith-ball. Does it imply that te pith-ball is negatively charged?

When a positively charged rod is kept in contact with an insulated metal, the electrons move from the ........
