(a) - (i), (b) - (iii), (c) - (iv), (d) - (ii) (i) The value of acceleration due to gravity ' g ' at height ' h ' is expressed as ( gh _ h = g (1- 2 ~h R ) ) (ii) The value of acceleration due to gravity ' g ' at depth ' h ' is expressed as ( g _ d = (1- h R ) ) (iii) The value of acceleration due to gravity at poles is maximum. The value of acceleration due to gravity is minimum at the equator of the earth. (iv) The relation between acceleration due to gravity and Universal gravitational constant is given by ( g =
