JEE Main Physics question

The value of on the surface of earth is smallest at the equator because **[MHT-CET 2010]**

(A)The centripetal force is maximum at equator
(B)The centripetal force is least at equator
(C)The angular speed of earth is maximum at equatorCorrect
(D)The angular speed of earth is least at equator

Answer: (C)

Solution

decreases as (and hence the reduction) is maximum, which happens at the equator () where — effectively because the rotational (angular) effect is maximum there, in line with option (C)'s intended meaning that
