Correct Answer - Option 4 : In the Antarctic Camp
The correct answer is In the Antarctic Camp.
- In the Antarctic Camp, the value of 'g' (gravity) is the highest.
-
Gravity:
- The acceleration due to gravity is the rate of increase of velocity of a body falling freely towards the earth.
- It is represented by \(g= {GM_e \over R^2_e}\).
where Me is the mass of the earth and Re is the radius of the earth.
- The value of g at the surface of the earth is 9.8 m/s2.
- Variation in g:
- Value of g decreases with height or depth from the earth’s surface.
- g is maximum at poles. Hence, it will be maximum at the Camp in Antarctica
- g is minimum at the equator.
- g decreases due to the rotation of the earth.
- g decreases if the angular speed of earth increases and increases if the angular speed of earth decreases
- The value of g on the Moon is 1/6th of that on the earth.
