Question



Coriolis acceleration of a particle over the Earth's surface depends on: (A) Angular velocity of Earth (B) Mass of the particle (C) Latitude of the location (D) Velocity of the particle (E) Longitude of the location
Choose the correct answer from the options given below:

A.

(A), (B) and (C) Only

B.

(A), (C) and (D) Only

C.

(A), (D) and (E) Only

D.

(A), (B), (C) and (D) Only

Correct option is B

Explanation:
The Coriolis acceleration is an apparent force experienced by an object moving within a rotating reference frame — like the rotating Earth.
The formula for Coriolis acceleration is:
ac​=2v×ω⋅sin(ϕ)
Where:
· v = velocity of the particle
· ω = angular velocity vector of Earth
· ϕ = latitude
Therefore, Coriolis acceleration depends on:
· (A) Angular velocity of Earth (ω\omegaω)
· (C) Latitude (ϕ\phiϕ)
· (D) Velocity of the particle (vvv)
It does not depend on:
· (B) Mass of the particle — Coriolis acceleration is independent of mass
· (E) Longitude — Longitude does not directly influence the Coriolis effect
Information Booster:
· The Coriolis effect causes the deflection of moving air and water — to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.
· Strongest at the poles and zero at the equator due to dependence on sin(ϕ).
Additional Information:
· (a) includes mass — which is incorrect.
· (c) includes longitude — which doesn't affect the Coriolis force.
· (d) incorrectly includes mass again.
