Question 35: Gravitation

Question

If the earth were to spin faster, acceleration due to gravity at the poles

Accepted Answer

The variation of g with angular velocity $$\omega$$ is given by
$$g'=g-R\omega^2$$
If earth were to spin faster, that is angular velocity increases, then except at poles, the weight of bodies will decrease at all places.

Answer

increases

Answer
