    John pushes a table with wheels under it. At the same time, Abraham pushes a table without any wheels under it. Both the .tables weigh the same. The two tables move at the same speed, but John applies lesser force than Abraham.
    Which force is reduced by the wheels under John's table?

    A)  Magnetic          

    B)  Frictional

    C)  Electrostatic                     

    D)  Gravitational

    Correct Answer: B

    Solution :

      Frictional force always opposes the motion of a body. This force can be reduced by using wheels under the moving body. Wheels under John?s table reduce the surface of contact between the floor and the table. As a result, frictional force between the table and the floor decreases. The correct answer is B.
