Acceleration due to gravity and its variation

Question

Spot the wrong statement :The acceleration due to gravity ‘g’ decreases if

Easy

A

We go down from the surface of the earth towards its centre
B

We go up from the surface of the earth
C

We go from the equator towards the poles on the surface of the earth
D

The rotational velocity of the earth is increased

Solution

Value of g increases when we go from equator to poles
$\Rightarrow g_{λ} = g - R ω^{2} \cos^{2} λ, i f ω i n c r e a s e s g d e c r e a s e s$ .
