A 40-N force is applied horizontally to box A, while the same force is applied at an angle to box B. Let WA be the work done by the 40-N force on box A as it travels a horizontal distance of 5 m across the floor. Let WB be the work done by the 40-N force on box B as it travels a horizontal distance of 5 m across the floor. Which of the following is true?

  1. WA < WB
  2. WA = WB
  3. WA > WB
