Given below are two statements:
Statement $I:$ Acceleration due to earth's gravity decreases as you go 'up' or 'down' from earth's surface.
Statement $II:$ Acceleration due to earth's gravity is same at a height ' $h$ ' and depth ' $d$ ' from earth's surface, if $h = d$.
In the light of above statements, choose the most appropriate answer form the options given below
A
Statement $I$ is incorrect but statement $II$ is correct
B
Both Statement $I$ and Statement $II$ are incorrect
C
Statement $I$ is correct but statement $II$ is incorrect
D
Both Statement $I$ and $II$ are correct
(JEE MAIN-2023)
Solution
$g ^{\prime}=\frac{ g }{\left(1+\frac{ h }{ R }\right)^2}$
$g^{\prime} = g 1-\frac {d }{R}$
Statement $I$ is correct and Statement $II$ is incorrect
