    When a body falls in air, the resistance of air depends to a great extent on the shape of the body. 3 different shapes are given. Identify the combination of air resistances which truly represents the physical situation. (The cross sectional areas are the same).                      

    A)  1 < 2 < 3

    B)  2 < 3 < 1

    C)  3 < 2 < 1

    D)  3 < 1 < 2

    Correct Answer: C

    Solution :

    Fig. 3 is stream lined, so air resistance for it will be minimum. For fig. 1 surface area is maximum, so air resistance for it is maximum. Hence correct sequence is 3 < 2 < 10
