A positively charged rubber rod is moved close to a neutral copper ball that is resting on a nonconducting sheet of plastic. a) Sketch the distribution of the charges on the ball. b) With the rod still close to the ball, a metal wire is briefly connected from the ball to the earth and then removed. After the rubber is rod is also removed, sketch the distribution of charges(if any) on the copper ball.

We cannot draw sketches for you. Refer to a website that discusses charge by induction, and which has figures.

Refer to the left-hand part of figure 22.2 of the site below for a sketch of what happens.
