After a great many contacts with the charged ball, how is any charge on the rod arranged (when the charged ball is far away)? there is positive charge on end b and negative charge on end a. there is negative charge spread evenly on both ends. there is negative charge on end a with end b remaining neutral. there is positive charge on end a with end b remaining neutral. the conducting rod is not grounded, so a negative charge accumulates on one end, but a charge cannot remain at a single end in a conductor, so it will spread to both ends: there is negative charge spread evenly on both ends

A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p
