Question

The place where the value of 'g' is unaffected by the increase (or) decrease in the speed of rotation of the earth about its own axis is poles

• A. True
• B. False

Answer 1

The correct option is A True

effective value of g is given by $\frac{GM}{r^2}-{\omega }^{2}r$

so if value of g is independent of $\omega$ the r needs to be zero. i.e. point is on axis of rotation.

then we can say that at poles g is unaffected by change in speed of rotation.

so given statement is true.
