(C) The effective acceleration due to gravity $g'$ at a latitude $\lambda$ is given by $g' = g - \omega^2 R \cos^2 \lambda$,where $\omega$ is the angular velocity of the earth's rotation and $R$ is the radius of the earth.At the poles,the latitude $\lambda = 90^\circ$. Substituting this into the formula,we get $g' = g - \omega^2 R \cos^2(90^\circ) = g - 0 = g$.Since the value of $g'$ at the poles is independent of the angular velocity $\omega$,the weight of a body $(w = mg')$ will not change if the earth stops rotating on its own axis.Therefore,there will be no variation in the weight of our bodies at the poles.

If the earth stops rotating on its own axis,there will be no variation in the weight of our bodies at:
