Physics Gravitation Statement Based MCQ (Single Correct)

Given below are two statements:

Statement I: Rotation of the earth shows effect on the value of acceleration due to gravity (g).

Statement II: The effect of rotation of the earth on the value of g at the equator is minimum and that at the pole is maximum.

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

Statement I is false but statement II is true

Both Statement I and Statement II are true

Both Statement I and Statement II are false

Statement I is true but statement II is false

Text Solution

Verified by Experts

The correct answer is:

The variation of acceleration due to gravity with the rotation of Earth can be written as

...

Substitute 0° for for equatorial position to obtain the acceleration due to gravity.

Substitute 90° for for polar position to obtain the acceleration due to gravity.

The above two equations show that the effect on acceleration due to gravity is maximum at the equator and minimum at pole.
