Where will a body weigh more - 1 km above the surface of earth or 1 km below the surface of earth?

Answer:

                As \[{{g}_{h}}=g\left( 1-\frac{2h}{d} \right)\]  and \[{{g}_{d}}=g\left( 1-\frac{d}{h} \right)\]                 For \[h=d=1km,\]clearly \[{{g}_{d}}>{{g}_{p}}\]. Hence the body will weigh more at a depth of \[\text{1 km}\] below the surface of earth.
