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).
Text Solution
Verified by ExpertsThe correct answer is:
C
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 
.
