In five seconds, a point charge moves from position A to position B as shown in the diagram below. Which one of the following two paths require the most energy? 
  • a)
    Both paths require an equal amount of energy because work is independent of the path.
  • b)
    Both paths require an equal amount of energy because they both complete the same displacement in position in the same amount of time.
  • c)
    Path #1 requires more energy because it directly opposes the electric field.
  • d)
    Path #2 requires more energy because it moves the point charge through a longer distance.
Correct answer is option 'A'. Can you explain this answer?

In five seconds, a point charge moves from position A to position B as...
  • The amount of time is not relevant to this problem.
  • In electrostatics, energy is determined by product of the point charge magnitude, the displacement of the point charge, and the value of the electric field, for a constant field in the direction of displacement:
    W = Fd
    W = qEd
  • When the displacement is the same for both paths of a point charge along a constant electric field, the energy expended is equivalent.
