At the centre of the earth, the value of g becomes:
Correct answer: A. Zero
- A. Zero
- B. Infinity
- C. 9.8 ms-2
- D. None of the above
Explanation
At the center of the Earth, the value of gravitational acceleration (g) becomes zero. This is because, at the center, the mass above cancels out the gravitational forces from all directions, resulting in a net gravitational force of zero.
