A negatively charged body is brought to an uncharged metal ball connected by a conductor to the Earth without touching the ball. Will the ball interact with a charged body, and if so, how? After that, the conductor is disconnected from the ball and removed. Will the ball now interact with a charged body, and if so, how? Explain the answer.
The ball will be attracted to the body, because the electrons go through the conductor to the ground. the ball will remain positively charged.
