Let the acceleration due to gravity be \( g_{1} \) at a height \( h \) above the Earth's surface, and \( g_{2} \) at a depth \( d \) below the Earth's surface. If \( g_{1}=g_{2}, hR \), and \( dR \), then
(A) \( h=d \)
(B) \( h=2 d \)
(C) \( 2 h=d \)
(D) It is not possible for \( g_{1} \) to be equal to \( g_{2} \).
