Vedclass · Answer

(A) The effective acceleration due to gravity $(g')$ is given by the formula $g' = g - \omega^2 R \cos^2 \lambda$,where $\omega$ is the angular velocity of the earth,$R$ is the radius of the earth,and $\lambda$ is the latitude.If the earth stops rotating,$\omega = 0$,which means the term $\omega^2 R \cos^2 \lambda$ becomes zero.Consequently,the effective gravity $(g')$ increases at all points except at the poles (where $\lambda = 90^\circ$ and $\cos 90^\circ = 0$).Since weight $(W = mg)$ is directly proportional to the effective acceleration due to gravity,the weight of a body will increase at all locations on the earth's surface except at the poles,where it remains unchanged.

What would be the effect on the weight of a body if the earth stopped rotating?
