Using gravitational law, F = G(m1)(m2)/r^2, where m1 is the mass of the earth = 5.9742x10^24kg, m2= mass of the man = 900/9.81 = 91.74kg, the r is the distance between the man and the center of the air and it is equal to (6378km+9000m = 6387km), this
Pretty sure the previous answer is incorrect, as the man's head wouldn't be three times as far under the ground as far it is above the ground now.
