Considering rotational motion of earth. The acceleration due to gravity at the equator of earth is given by, (where

\omega=

angular velocity of earth,

\mathrm{R}=

radius of earth,

\mathrm{g}=

acceleration due to gravity)

View answer and explanation

Correct option: C

\mathrm{g}^{\prime}=\mathrm{g}-\omega^2 \mathrm{R}

Option C (

\mathrm{g}^{\prime}=\mathrm{g}-\omega^2 \mathrm{R}

) is correct because the effective acceleration due to gravity at the equator is reduced due to the centrifugal force caused by Earth's rotation.
