हिन्दीConsider the following statements regarding the acceleration due to gravity of Earth: (A) At the centre of the Earth, the acceleration due to gravity is zero. (B) For a height \( h \ll R_E \), the acceleration due to gravity is given by \( g(h) \approx g(1 - 2h/R_E) \). (C) The acceleration due to gravity increases linearly as one goes deeper into the Earth. (D) The value of \( g \) is maximum at the surface of the Earth. Which of the above statements are correct?
Correct answer · Option 4
(A), (B) and (D) only
Explanation
\( g(d) = g(1 - d/R_E) \), so \( g \) decreases linearly with depth and is zero at the centre. Thus (A), (B), and (D) are correct, while (C) is incorrect.
