Sorry, can one of you guys explain where this is wrong:
1. Gravitational acceleration on Earth is 9.81m/s. Therefore if weight is 1/100, gravitational accleration is 0.0981m/s.
2. We know that acceleration=(GmE)/(rE)^2
3. Sub in 0.0981=(6.67x10^-11)x(5.97x10^24)/(r)^2
4. Solve for r and subtract...
