I am working on a problem to sate my own curiosity. :) My mass is approximately 85.1 Kg. The Earth's mass is approximately (5.972x10^24 kg) and the distance between our center of masses is roughly the same as the Earth's radius of (6371 km) so I was wondering; what would the earth's gravitational force be between the two of us. My answer is 8.3514...x10^8 N (Using the formula: F=G ( (m1xm2)/r^2) ) Am I correct? Thank you!
