    At an amusement park, a capsule in a free fall tower ride has a huge magnet fitted to its base. The capsule is prevented from hitting the ground by a powerful magnet, placed at the bottom of the ride. The magnet that faces upward has the same pole as the magnet that faces downward.
    Which force prevents the capsule from hitting the ground?

    A)  Gravitational                    

    B)  Magnetic

    C)  Electric                

    D)  Nuclear

    Correct Answer: B

    Solution :

      The magnet placed at the bottom of the ride repels the magnet that is fitted below the capsule, as both have the same poles facing each other. This causes the ride to slow down as it reaches the surface because magnetic repulsions increase as the distance between the base of the ride and the capsule decreases. The correct answer is B.
