Vedclass · Answer

(C) The acceleration due to gravity $g$ is given by $g = \frac{GM}{R^2}$. $1$. As we go down towards the center of the earth,$g$ decreases. $2$. As we go up from the surface of the earth,$g$ decreases. $3$. As we move from the equator towards the poles,the radius of the earth $R$ decreases,which causes $g$ to increase. Therefore,the statement that $g$ decreases when moving from the equator to the poles is incorrect. $4$. If the rotational velocity of the earth increases,the centrifugal force increases,which causes the effective value of $g$ to decrease. Thus,option $C$ is the incorrect statement.

Column-$I$	Column-$II$
$(1)$ Maximum value of acceleration due to gravity $g$	$(a)$ At the center of the Earth
$(2)$ Minimum value of acceleration due to gravity $g$	$(b)$ At the poles
$(3)$ Zero value of acceleration due to gravity $g$	$(c)$ At the equator

Identify the incorrect statement. The acceleration due to gravity $g$ decreases if:
