MCQ

Given below are two statements :

Statement$-I:$ Acceleration due to gravity is different at different places on the surface of earth.

Statement$-II:$ Acceleration due to gravity increases as we go down below the earth's surface.

In the light of the above statements, choose the correct answer from the options given below

A
Both Statement $I$ and Statement $II$ are true
B
Both Statement $I$ and Statement $II$ are false
✓
Statement $I$ is true but Statement $II$ is false
D
Statement $I$ is false but Statement $II$ is true

✓

Answer

Correct option: C.

Statement $I$ is true but Statement $II$ is false

c
$g_{e f f}=g-\omega^2 R_e \sin ^2 \theta, \theta \rightarrow$ co-latitude angle

$g_{e f f}=g\left(1-\frac{d}{R_e}\right), d$ here depth
