    An experiment was conducted to find the amount of force needed to move a 100 g load over different surfaces. Which one of the following scales would show the smallest reading?

    A)  

    B)

    C)

    D)  

    Correct Answer: D

    Solution :

    Smooth surfaces like glass offer least resistance as the friction produced is less. It is easy to move the weight on a glass surface as it is smoother than other materials. Hence, the reading on this scale would be the smallest.
