QUESTION:
Consider a ring of radius R with the total charge Q spread uniformly over its perimeter. What is the potential difference between the point at the center of the ring and a point on its axis a distance 2R from the center?
ANSWER:Step 1 of 3
Electric potential is the amount of work required for moving the unit positive charge from the infinity to some reference point.
Here is the potential difference between the points and , is the work done by the field in moving a test positive charge from to .
