Suppose that in the third law experiment, you attach the magnetic bumpers on both carts and place them on the track so that the two carts repel each other. Also suppose that the red cart's magnets are twice as strong as the blue cart's. Then as you hold one cart at fixed position, and push the other towards it, they will repel each other, and you note the forces on the two carts (i. e. their bumpers). Which of the following would be true? a. Force on both carts will be equal.
b. Force on the red cart will be more than on the blue cart.
c. Force on the blue cart will be more than on the red cart
d. Forces will depend on which cart is held fixed, and which one is pushed.
