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

A

`1lt2lt3`

B

`2lt3lt1`

C

`3lt2lt1`

D

`3lt1lt2`

Text Solution

Verified by Experts

The correct Answer is:
C
Figure `3` is streamlined, so air resistance of it will be minimum. For figure 1 surface area is maximum, so air resistance for it is maximum.
Hence, correct sequence is `3lt2lt`.
