Question 4

Given below are two statements:
Statement I: Rotation of the earth shows effect on the value of acceleration due to gravity $$(g)$$.
Statement II: The effect of rotation of the earth on the value of $$g$$ at the equator is minimum and that at the pole is maximum.
In the light of the above statements, choose the correct answer from the options given below

Statement I: True. Earth's rotation affects g: $$g' = g - \omega^2 R\cos^2\lambda$$.

Statement II: The effect is maximum at the equator ($$\cos^2 0° = 1$$) and minimum (zero) at the poles. So Statement II says the opposite, which is false.

The correct answer is Option 4: Statement I is true but Statement II is false.
