  • question_answer
    A box was pushed equal distance on four different surfaces. The force needed for each surface was recorded in the given table.
    Surface M N O P
    Force Needed (N) 670 570 320 500
    On which surface was the friction least?

    A)  M                               

    B)  N                    

    C)  O                                

    D)  P

    Correct Answer: C

    Solution :

    Friction opposes the motion of an object. For surface O, force needed to push the box is least i.e., 320 N, so it has least friction.
