Cherise sets identical magnetic carts on two tracks. At the end of each track is a blue magnet that cannot move. Cherise can move the carts one space to the left or one space to the right. Which movement will result in the largest increase in potential energy?
A. Moving the cart on Track 1 one space to the right (→).
B. Moving the cart on Track 2 one space to the left (←).
C. Moving the cart on Track 2 one space to the right (→).
D. All these movements will result in the same change in potential energy because they each move a cart the same distance.
c. Moving the cart on Track 2 one space to the right (→).
