Physics · GRAVITATION
हिन्दीAt what depth \( d \) below the Earth's surface does the acceleration due to gravity reduce to half of its value at the Earth's surface \( g \)? (Take radius of Earth as \( R_E \))
Correct answer · Option 2
\( \frac{R_E}{2} \)
Explanation
Using g(d) = g (1 - d / R_E), setting g(d) = g / 2 gives 1 - d / R_E = 1/2, so d = R_E / 2.
