Choose the correct alternative:
$(a)$ Acceleration due to gravity increases/decreases with increasing altitude.
$(b)$ Acceleration due to gravity increases/decreases with increasing depth.
$(c)$ Acceleration due to gravity is independent of the mass of the earth/mass of the body.
$(a)$ Acceleration due to gravity increases/decreases with increasing altitude.
$(b)$ Acceleration due to gravity increases/decreases with increasing depth.
$(c)$ Acceleration due to gravity is independent of the mass of the earth/mass of the body.
(A) Acceleration due to gravity decreases with increasing altitude because $g' = g(1 - 2h/R_e)$ for small heights.
$(b)$ Acceleration due to gravity decreases with increasing depth because $g' = g(1 - d/R_e)$.
$(c)$ Acceleration due to gravity is independent of the mass of the body,as $g = GM/R^2$,where $M$ is the mass of the Earth and $R$ is its radius.
$(b)$ Acceleration due to gravity decreases with increasing depth because $g' = g(1 - d/R_e)$.
$(c)$ Acceleration due to gravity is independent of the mass of the body,as $g = GM/R^2$,where $M$ is the mass of the Earth and $R$ is its radius.
