Question

At a point where the electric potential is 400 V, a positive charge is moving to the left. As the charge continues to move, it slows down, stops, and then begins to move back to the right. Using what is shown, its speed as it passes its initial position is
A. Greater than its initial speed. B. Less than its initial speed.
C. Equal to its initial speed. D. There is not enough information to tell.

FIGURE 21.7 A charged particle speeds up or slows down as it
moves through a potential difference.
KEY CONCEPT
(a) A positive charge speeds up (AK>0) as
it moves from higher to lower potential
(AV < 0). Electric potential energy is
transformed into kinetic energy.
(b) A positive charge slows down (AK< 0)
as it moves from lower to higher potential
(AV> 0). Kinetic energy is transformed
into electric potential energy.

After: i
| Before:
AV=+100 V > 0
A double-headed green arrow is used to
represent a potential difference.
AV =-100 V <0
· Dashed green lines are lines of constant
electric potential. The potential is 500 V
at all points on this line.
