**Damon**, Tuesday, October 14, 2008 at 8:15pmF = G Me m/R^2

Fe= G Me m/Re^2

F/Fe = 11/100 = 1/R^2 / 1/Re^2 = Re^2/R^2

11/100 = Re^2/R^2

R/Re = sqrt(100/11) = 10/sqrt 11

= 3.01

so

R = 3.01 Re

**drwls**, Tuesday, October 14, 2008 at 8:17pmThe force of gravity is proportional to 1/r^2, where r is measured from the center of the earth. Therefore

(r/rE)^-2 = 0.11

r/rE = sqrt (1/0.11) = sqrt 9.09 = 3.015
