Question

Decrease in the value of acceleration due to gravity at a height of 96km from the earth' surface is ???
(a) 30cm/s (b) 15cm/s
(c)20cm/s. (d)60cm/s

Answer 1

the value of acceleration due to gravity will 9.506 m/s^2

initially it was 9.8 m/s^2 .

decrease in value = 9.8-9.506 = 0.294 m/s^2

                                                   ~30 cm/ s^2

hope it helps,,
