MCQ
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
  • ✓
    Statement $I$ is correct but statement $II$ is incorrect
  • D
    Both Statement $I$ and $II$ are correct
✓

Answer

Correct option: C.
Statement $I$ is correct but statement $II$ is incorrect
c
$g ^{\prime}=\frac{ g }{\left(1+\frac{ h }{ R }\right)^2}$

$g^{\prime} = g 1-\frac {d }{R}$

Statement $I$ is correct and Statement $II$ is incorrect
