Question

With reference to "Coriolis force”, which of the
following statements is/are correct?

1. It increases with increase in wind velocity.

2. It is maximum at the poles and is absent
at the equator.

Select the answer using the code given below :

Accepted Answer

1. **Statement 1 is correct.** The magnitude of the Coriolis force (F_c) is directly proportional to the velocity of the moving object (v). The formula for Coriolis force is F_c = 2mvΩsinφ, where m is mass, v is velocity, Ω is angular velocity of Earth's rotation, and φ is latitude. As 'v' (wind velocity in this context) increases, the Coriolis force increases.

2. **Statement 2 is correct.** From the formula F_c = 2mvΩsinφ:
* At the **poles**, latitude (φ) is 90° (or -90°), and sin(90°) = 1. This means the Coriolis force is at its maximum at the poles (F_c = 2mvΩ).
* At the **equator**, latitude (φ) is 0°, and sin(0°) = 0. This means the Coriolis force is zero, or effectively absent, at the equator (F_c = 0).

Therefore, both statements are correct.
