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
  • ✓

  • D
    Statement $I$ is false but Statement $II$ is true
✓

Answer

Correct option: C.
Statement $I$ is true but Statement $II$ is false
