Part A

How far would you have to drill into the Earth, to reach a point where your weight is reduced by 8.0\% ? Approximate the Earth as a uniform sphere.

g= GMe/re^2

g'=.92GMe/re^2 =GMe(r/re)^3

then it reduces to

.92re=r^3, and that leads to

r=re *cubrt(.92)

the r is, 6205.11, and shouldn' t I need to subratc it from radius of earth which is 6380-6205.11, it is equal to "174.89" but my answer fails. Please help, ty for ur care now.
