Problem

Choose the correct order of the magnitude of acceleration due to gravity at three altitudes:

h_1 = R

h_2 = 2R

, and

h_3 = 3R

above the Earth’s surface (where

R

is Earth’s radius). a)

g_{h_3} > g_{h_2} > g_{h_1}

g_{h_1} > g_{h_2} > g_{h_3}

g_{h_1} = g_{h_2} = g_{h_3}

g_{h_2} > g_{h_1} > g_{h_3}
