Step-by-Step Verified Solution
Let at h height, the weight of a body becomes 1/16th of its weight on the surface.
W h = 16 W s ...(i)
_ 16 W s = W s ...(ii)
W h = m g = G M m ( R e + h ) 2
g _ = G M ( R e + h ) 2
Similarly, g = G M R e 2
g _ g = R e 2 ( R e + h ) 2 _ g _ = g ( 1 + h R ) _ 2
_ W h = 16 W s
_ g _ = g 16
1 16 = ( 1 + h R ) _ 2 _ 4 = 1 + h R
h = 3R
