Acylindrical can of radius r is rolling across a horizontal surface without slipping.
(a) after one complete revolution of the can, what is the distance that its center of mass has moved?
(b) would this distance be greater or smaller if slipping occurred?

Imagine that the rightward current flows in the rod for a short time. as a result, what will the net charge on the right and left ends of the rod become? left end negative and right end positive left end negative and right end negative left end negative and right end nearly neutral left end nearly neutral and right end positive both ends nearly neutral
