Question

The values of g at six distances A, B, C, D, E and F from the surface of the earth are found to be 3.08 m/s2, 9.23 m/s2, 0.57 m/s2, 7.34 m/s2, 0.30 m/s2 and 1.49 m/s2, respectively.
(a) 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)
(b) If the value of distance F be 10000 km 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.

Solution

a) As `g ∝ 1/r^2` , hence the value of g, according to the increasing distances from the earth, are as follows: 9.23 m/s27.34 m/s2, 3.08 m/s2, 1.49 m/s2, 0.57 m/s2, 0.30 m/s2
b) The place would be high up in the sky because the earth’s radius is 6,400 km which is lesser than 10000 km.

  Is there an error in this question or solution?
