Assume a uniformly charged ring of radius R and charge Q produces an electric field Ering at a point P on its axis, at distance x away from the center of the ring as in Figure OQ23.13a. Now the same charge Q is spread uniformly over the circular area the ring encloses, forming a flat disk of charge with the same radius as in Figure OQ23.13b. How does the field Edisk produced by the disk at P compare with the field produced by the ring at the same point?
 
Question 2

What kinematic concept (distance, velocity, acceleration, etc.) of the moving object does the slope of the graph represent?
