Problem

An object is taken to a depth of

800\,\text{km}

below Earth’s surface and to a height of

800\,\text{km}

above the surface (assume

800\,\text{km} \ll R

). Which statement about the magnitudes of the acceleration due to gravity at these two locations is correct? a)

g_{\text{altitude}} = g_{\text{depth}}

g_{\text{altitude}} > g_{\text{depth}}

g_{\text{altitude}} < g_{\text{depth}}

d) Both are equal to the surface value

g
