A) There will be no change in weight anywhere on the earth
B) Weight of the object, everywhere on the earth, will decrease
C) Weight of the object, everywhere on the earth, will increase
D) Except at poles, weight of the object on the earth will decrease
Correct Answer: D
Solution :
Effect of angular velocity on acceleration due to gravity is given by \[{{g}^{0}}=g-{{\omega }^{2}}R\cos \theta \] so with increase in the decreases but at poles \[\theta ={{90}^{o}};cos\theta =0\]so \[{{g}^{0}}=g\]
