Consider a Motion in Which a Particle Goes from A \to

question 61

Multiple Choice

Consider a motion in which a particle goes from A $\to$ B along path 1 and from B back to A along path 2, as shown.
W(AB, 1) = work in going from A $\to$ B along path 1.
W(BA, 2) = work in going from B $\to$ A along path 2.
If only conservative forces are acting, then

• A) W(AB, 1) > W(BA, 2)
• B) W(AB, 1) < W(BA, 2)
• C) W(AB, 1) + W(BA, 2) > 0
• D) W(AB, 1) + W(BA, 2) < 0
• E) W(AB, 1) + W(BA, 2) = 0
