Question

Which of the following is/are methods to find the direction of wind at a given place?

Options:

A . By observing the direction in which the kite sways.

B . By observing the direction in which a flag flutters.

C . By freely suspending a N-S pole magnet

D . Throwing small pieces of paper and observing the direction in which it flows.

Answer: Option A
:
A, B, and D

In the kite, flag and paper-piece experiment, the force which is responsible for the action is the pressure exerted by the wind. While considering the magnet example we can see that the force taken into consideration is magnetic in nature, hence this experiment cannot be used to determine the direction of wind.
