The values of g at six distances A, B, C, D, E and F from the surface of the earth are found to be 3.08m/s2, 9.2.3m/s2, 0.57m/s2, 7.34m/s2, 0.30m/s2 and 1.49m/s2, respectively.

  1. Arrange these values of g according to the increasing distances from the surface of the earth (keeping the value of g nearest to the surface of the earth first).
  2. If the value of distance F be 10000km from the surface of the earth, state whether this distance is deep inside the earth or high up in the sky. Give reason for your answer.
