A) \[\frac{{{R}_{E}}}{3}\]
B) \[2\,\,\frac{{{R}_{E}}}{3}\]
C) \[\frac{{{R}_{E}}}{3}\]
D) \[\frac{{{R}_{E}}}{4}\]
Correct Answer: B
Solution :
Acceleration due to gravity at a depth d is \[g'=g\left[ 1-\frac{d}{{{R}_{E}}} \right]\] \[\Rightarrow \] \[\frac{g}{3}=g\left[ 1-\frac{d}{{{R}_{E}}} \right]\] or \[d=\frac{2}{3}{{R}_{E}}\]
